Surreal Higgs Bumps The LHC

Alan Gillis Reports   ¿Es macho el Higgs o no es macho? Did Alexander Calder discover the Higg's boson while inventing the Large Hadron Collider? Well, anything is possible in Quantum mechanics. Physicists at CERN have always been closet Surrealists. Their latest hat trick, Run Rabbit Run, a brand new particle, possibly the one they were looking for. Though it will take more analysis and more experimental data and maybe even a new cleaner very high energy electron-positron collider to find out. The Higgs is an important particle and central to Standard Model physics if it exists. The Higgs has to be nailed or the SM collection of interlocking theories is flawed. Without the Higgs the SM cannot account for the mass of the Universe. Ergo non fiat, no Ferrari in any CERN parking lot. And that's impossible and might start a trend if $10 Billion is not enough to prove anything.

All CERN has for sure is a new particle that looks like a Higg's candidate. And the Higgs may not be fundamental after all, only responsible for a small amount of the mass of the Universe. See the "Higgs Fandango" below.

Chorus from The Rain In Spain ...

“As a layman, I would now say, I think we have it,” said CERN Director-General Rolf-Dieter Heuer (back row 2nd from left, Peter Higgs in front) announcing the preliminary results July 4. “It’s a historic milestone today. I think we can all be proud, all be happy.”

Anyway after 50 years of slaving over hot colliders, you can't blame physicists if they're partying now. It's great for morale and with the whole world watching the party, the applause from enraptured physicists, the Champagne flowing, well it's a relief for any physicist just to be human again.

Then it's the post-collider hangover and maybe we over did it. A heavy particle at 125 GeV or about the mass of an iodine atom looks good in the data but Dr Heuer clarifying "it" as a "fundamental scalar boson"? Sounds like Premature Collider Evacuation Syndrome where circumlocution pops out a Higgs, but with no conclusive evidence for scalar or zero spin from these bosons at the LHC.

The WW decay data channel should tell CERN that the Higgs decays into two W bosons indicating it is the SM Higgs with zero spin, but there is a deficit in this data both in the CMS and ATLAS experiments.

Lots of types of decays happen too and there are other puzzling deficits. Here's the research from ATLAS on what's been discovered in all channels.

There's an odd excess too. The diphoton decay channel for this new boson shows many more photon events than was predicted for the Higgs. Here's the latest diphoton data from ATLAS in pdf.

Higgs? Blasts Into 4 Muons

So it's premature to talk of any Higgs discovery. Maybe we have signals from one of a group of Higgs particles, but not from the Standard Model Higgs. Maybe it's just a new charged particle outside the Higgs group. Or even a composite particle. Two things we know for sure are more research is needed and CERN PR provides more spin than any known particle.

A Simple Higgs Experiment For The LHC

The mysterious Higgs and all from a vacuum too. So why not study the vacuum? CERN already has a space-type vacuum at a space temperature of near absolute zero in its 54 km (27 km x 2) beam pipe system. This heavy Higgs field has to be inside it if it's real. Run the LHC without the protons and see if you can excite the Higgs field with the RF system used to accelerate protons. But CERN does this anyway in any proton run. Both protons and any fields in the vacuum are being accelerated. You could say the data is in. No Higgs field has been excited or accelerated or collided or found. So is there a real Higgs field that exists everywhere? Not at the LHC. No says CERN, that's not how it works:

"Higgs bosons are quantum fluctuations in the Englert-Brout-Higgs field that are visible experimentally only when energy is “injected” into the field. Concentrating the right amount of energy in proton-proton collisions at the LHC excites the Englert-Brout-Higgs field, which resonates at a precise energy corresponding to the mass of the Higgs boson.  The Higgs boson appears momentarily before decaying into other particles that the LHC experiments can measure. Some theories predict the existence of multiple Higgs bosons."


The fundamental Higgs boson decays? So far all big particles discovered at colliders decay. Why? Well the short answer is because they can. That's one answer from Lily Asquith at ATLAS. But maybe these fundamental particles aren't fundamental, but unstable composites from the bottomless pit of collider physics.

Maybe the  E-B-Higgs field is unstable too. Then can CERN kick it with some energy to get a Higgs? Or is there another pathway if it is stable? An electron is stable and an electron field is stable. Do you need to kick the electron field with energy to produce an electron? Unstable particles would have no mother fields.  

What CERN says above, can be translated in another way. CERN strikes a Higgs high C "energy" from its SteinwayLHC that is "injected" into the totally quiet and invisible high C E-B-Higgs field where the energy "resonates" and "excites" the field and out pops an excited real world high C Higgs note that suddenly decays into other minor notes, sometimes 4 bright photons or a trill of mi-mi-mi-mi's etc etc.

Nonsense, as we know the air here is the field that resonates with high C but there are no high Cs in it that pop out. Don't need a collider to prove that at least. In either case, with or without a collider, is there any proof of a Higgs field?

If you don't think a musical analogy works, well CERN started it. Listen to "Higgs" for piano at ATLAS (Bravo!) based on an actual data graph or read more first on data sonification.

Collider Artifacts Of The Universe

Back to work. Nice theory CERN (in quotes above) on how energy (125 GeV) knocks a Higgs out of Higgs Space for us to see, but it is true? Recall the Big Bang in a vacuum? No fields before then and suddenly some super-condensed energy ball the size of an orange explodes, eventually producing everything including the Quantum fields presumably now in Spacetime where everything else is too including the LHC. Unless the LHC is in some hyper-reality because 10,000 physicists concentrate the LHC into a Higgs Player Piano or anything else they agree on just by a collective observer effect you do see in Quantum physics. Which could also be interpreted as a mass delusion like dancing orbs of light over Phoenix and other UFOs the Army always flatly denies. If only the Army reviewed LHC data? Not convincing guys. Call it a night. Your wives are waiting. OK so labcoats are confusing. CERN says 9% of their physicists definitely have larger breasts. See Fabiola over at ATLAS for details.

Shortfalls In CERN's Little Bang Machine

In reality however, the much hyped LHC Big Bang Machine or Little Bang frankly, is supposed to create similar conditions just a very tiny fraction of a second after the first BB explosion. Doesn't seem to be at all that similar. First thing you get is matter particles from high energy explosions that often decay into massless particles.

Blame that on the big Higgs field from the first BB. But then you really can't study the BB with CERN's Little Bang Machine. Fields from the BB are always interfering. Particles with mass seem to appear first and then some decay into particles without mass in these collider experiments. So the real object is not to make CERN PR a real world event, but to tease particles out from BB fields. Then why aren't there a lot of relatively low energy 125 GeV Higgs in all collider data? There aren't, indeed Higgs are extremely rare. Lower power but powerful enough colliders like the former Tevatron at Fermilab (RIP) and the still operating RHIC at Brookhaven should have seen them easily. Why does it take 8000 GeV (8 TeV) to produce a Higgs weighing 125 GeV? Well, there have been mysterious unconfirmed signals from other colliders including CERN's old LEP. But would the old data have been conclusive if it was processed by CERN's mighty computing center? Might have saved a few Billion dollars.

The new Mother Of All Colliders at CERN uses a sledge hammer to smash a mosquito to get one Higgs. Sorry, but CERN used to say they were smashing proton mosquitos together to make high energy physics look modest, familiar and safe.

Well CERN protons are heavy. When a proton at rest of 1 GeV (1 billion electron volts) is accelerated near light speed that adds a lot of mass. In the Higgs experiment CERN was using 4 TeV protons (4 trillion electron volts) meaning each proton punched 4,000 times above its rest mass weight for a collision energy of 8 TeV from just 2 protons. With on average 27 very very near simultaneous head-on collisions/explosions per 2 beam bunches crossing for collisions near twice the speed of light in a very tiny space, you get fireballs that explode. This isn't early days atom smashing. Though there is a lot of smashing due to focusing difficulties.

Millions of other collisions going on at the same time are off center elastic types, and these protons can smash each other to bits. What happens is already well known and this data noise is filtered and deleted. On a good day any of the 4 main experiments can achieve 100 million events each or more per second. But nearly all the data is noisy elastic collisions and so is discarded. Only interesting primary events are recorded for study.


Even so, there are mountains of interesting data that rush out so fast, the events have to be computer modeled if we want to see anything remotely like the original events. So it's complex software and vast computing power, that gives CERN its images and graphs and they are really only simplified schematics of strange but real events. An abstract of abstract events. How accurate are they? As good as the software, as clean as the original signals flowing through miles of fiber optics and copper wire and thousands of cores ganged together.

If you're a pro photographer working with RAW files and converters and then processing and enhancing images with various other software packages always being updated, you get the idea. No real definitive image of reality, just interesting versions. And if you didn't take the original shot yourself of something you've never seen with the shutter set to near light speed, capturing the very very insanely small, what is the image supposed to look like? What are we studying here?
 

Safety First But First The Higgs

In 2 years the LHC should reach its design objective of 14 TeV collisions a little later than planned. Hot on the trail of the Higgs on a giddy July 4th, everything else can wait. A year-long shutdown of the LHC for safety retrofits including more tinkering with weak magnets, has been delayed again, now for 3 months more, so as not to stop the LHC before Spring 2013. Fine except more safety systems after the $40 Million accident of 2008, were recommended and promised by CERN. Some safety modifications were made, and are working. But CERN is driving the collider hard, 24 hours a day.

Imagine an all electric Ferrari with an electrical short like last time. Imagine the mechanic says the liquid helium rad could still blow like last time. You want to go with a few tiny--don't mess with the collider--dimwit relief valves? You twist out some manometers for that? You need hundreds more of those in all 8 Sectors. Big ones are better remember? Gimme the big toot-toot ones you engineers said after the boom-boom-boom, when everything has got to be cooled down as cold as space. If not then it's boom-boom-boom again. This is a 10 Billion Dollar Machine. Safety first you say or gimme-dat Higgs?

As any old hand from the days of the Tevatron will tell you, every relief valve is a big problem. They leak all the time. And they blow all the time when helium pressure fluctuates as it does. And then beams dump and Cryogenic Havoc!

Could that be why CERN avoided installing them everywhere they should have before Catastrophic 2008? Nevermind, now we need them. A few tiny ones will do or maybe no collider for years. Safety, or as they might say in Collider Safety Committee meetings post-2008, Gentlemen we have a solution. Démarrons!


Vraiment? Well so far so good, but to get an idea what power one proton beam has at its eventual 7 TeV, imagine a Subaru travelling at 1712 kilometers per hour around the 27 km LHC ring tunnel. Then a second Subaru like the first but travelling in the opposite direction. All this from a little cc vial of hydrogen gas that's had its electrons stripped from its protons. 

Fortunately it's very difficult to collide protons head-on. From a pokey though much celebrated start, the LHC is now blazing. CERN keeps working up the numbers, hoping that at full power and luminosity it can get 600 million with hopes of a billion collisions per second. Though that's still a tiny fraction of the protons per beam. Yet if CERN loses control these beams can melt near a metric tonne of copper cooled to 2 degrees Kelvin (LHC beam vacuum is at 1.9 K) in a flash.  Or burn holes right through the collider and spill  liquid helium as instantly expanding cold gas that blows safety doors off their hinges. The LHC spilled tonnes of helium in the 2008 accident but due to other causes. Lost beams in a collider or runaway beams have happened before. A runaway beam of about 1 TeV at the Tevatron did cause major damage in 2003. See my article Major Failures At The Tevatron that also covers 1200 faulty relief valves.

Bottomless Pit Collider Physics

To return to what the LHC is for really. Evidently not a Big Bang Machine. No Big Bang yet, we're hoping. Not really a scalable model for the Big Bang either as BB fields distort experimental data. No way of extracting Big Bang data from a dingbat Little Bang Collider relying on Artificial Conditions that did not exist at the time of the Big Bang, like near light speed proton beams colliding head on in gigantic magnetic fields. American Baseball might be similar to English Cricket if you're a moron. So what kind of experiment is the LHC geared to?

Producing particles which it does. With more energy available than any other collider, then maybe new heavier particles. But perhaps this mania for the discovery of particles that need to be produced in colliders to be identified, as they cannot be found elsewhere in the real Universe, is an open-ended search that could produce an untold number of new particles that can exist temporarily in colliders and maybe exist elsewhere. Or don't exist elsewhere and may never have existed except inside rarefied and artificial environments like these gigantic fusion reactors that make them inside gigantic magnetic fields that CERN simply and modestly calls Detectors like CMS and ATLAS at the LHC.

If experiments are open-ended sooner or later the LHC could make dangerous collider objects like theoretically possible micro black holes. So far no experimental data show any being produced, but the race for higher and higher energy collisions at the LHC goes on. Up another big notch now from 3.5 TeV per proton beam to 4 TeV for collisions at 8 TeV and eventually to 14 TeV and that's Tera or Trillion electron Volts.

Proof positive of the Higgs is the main advertised event. But equally welcome to String theorists in the majority at CERN, are mBH from the LHC as Black Hole Factory, no longer advertised. Probable proof then of String theory and its extra dimensions and a chance to study elusive black holes, a quantum mechanical gold mine and a possible alternate for the Big Bang.

The LHC Demonstrates Einstein At Least

Waait a minute. Isn't something obvious going on at the LHC? About as simple as OxyClean on TV. Mysterious Quantum fields hiding in a vacuum are not needed to produce a Higgs or anything else. Just watch the LHC. Concentrate tremendous energies into a teeny bit of space and matter erupts from energy. The original Energy is transformed.

Happens all the time at the LHC. Isn't that what Einstein more or less implied with E=MC^2 ?

Do we even need a Higgs?

The Higgs Fandango 

Sure a particle might make sense inside a theory especially that partially predicts it, but is that why it's there? Can't the same particle fit into a better theory no one has invented yet, that explains that Theory H is suspect, because Particle H is really Particle Y which may be the case with the new Higgs Candidate. Theory H also doesn't predict the Higgs mass so any new boson lurking in the future with Spin0 might be the Higgs. The spectacular Higgs field is even stranger, everywhere, but nowhere we can find it. Thinking about mass for a minute, how does it account for the mass of an astronaut on the moon, one sixth of what it is on earth? Aha! Well physicists and CERN can answer that but don't often in all the brouhaha about the Higgs. Yes, you guessed it. There are other more important forces and the Higgs only accounts for a small amount of mass, like 1% of your body weight.

That's what they say at CERN behind closed doors. Gian Francesco Giudice, a CERN physicist, mentions it in his new book, A Zeptospace Odyssey: A Journey into the Physics of the LHC. Though you'll have to dig deep pp173-175.

"... the Higgs sector is rather arbitrary, and its form is not dictated by any deep fundamental principle. For this reason its structure looks frighteningly ad-hoc". Then he drops the other shoe, "It is sometimes said that the discovery of the Higgs boson will explain the mystery of the origin of mass. This statement requires a good deal of qualification.” And goes on to say, “In summary, the Higgs mechanism accounts for about 1 per cent of the mass of ordinary matter, and for only 0.2 per cent of the mass of the universe. This is not nearly enough to justify the claim of explaining the origin of mass.”
I think I just heard an explosion at Building 40, is it? From the CERN PR Machine.

The fundamental Higgs is not as important as advertised. So why fill the Universe with a Higgs field that doesn't do very much? Would CERN do that even if it could?

No, it's just not simple and elegant enough. Not Premium Grade A Physics.

Then why the Higgs circus at CERN? Why all this categorical rubbish about the importance of the Higgs? Sounds like stamp collecting for physicists, the rare penny black Higgs, but there's a serious Nobel on the horizon and more funding, certainly. In the end it's the not very likely and in basic energy terms very expensive Higgs field with little effect on the cosmos, with the very big question of gravity, unresolved.

The Higgs Key To Gravity? H to 4e

Unless the Higgs is really a graviton and in that case it can also account for the missing 1%, plus all the mass in the Universe which then also happens to be relative. Then we have an astonishing discovery and Alan Gillis should get the Nobel.
     

Nevermind, CERN Like Any Housewife Wants More

Let's face it Higgs are great but what every String theorist wants is funding and a real mBH for a thesis or a knock'em dead paper. In this Brave New World finally all String theorists are proved exactly right, and that's most physicists at the LHC. Except what would mBH do? Decay says Hawking and CERN. Or you can't produce mBH says CERN at the rock bottom On Sale Now new low power LHC, confidently invoking Einstein to cool down earlier PR and excited String theorists. Other worst case scenarios aren't taken seriously as real risks.

Anything new is interesting too. Some strange particles or collider objects may have been already created by colliders. If you don't know what to look for, you might miss them entirely. Always a career risk, but there are always more particles.

If the subdetectors in the big Detectors aren't specific enough to unknown particles or the magnetic fields aren't strong enough for containment, you could lose particles you never even dreamed of. Or maybe some physicists fast asleep have found Mt Blanc closed due to strange matter "tomato paste", leaving CERN ski teams baffled. We don't really know if it's strange matter yet.

CERN has built a CASTOR detector hitched to CMS for not expected but possible events, just in case. Then the unexpected can be familiar like a bus and yet knock you down, going the wrong way down a one-way street. Unexpected Symmetry breaking if you aren't looking both ways. Or something totally unexpected as we don't yet have an infinite number of theories to cover everything happening and anything can happen in Quantum mechanics.

No one wants that many theories of course, just one Theory of Everything that includes the big fields outside, like the gravity of the Universe and now theoretical dark energy and dark matter.

Or on the quest for ToE, have physicists simply reached the end of their mindset? Now padding reality with theories and inventing collider particles to prove them? Maybe it's as simple as going off on the wrong foot, in the wrong direction. Going into the maze that has no end, when maybe you should have stopped at the Starbucks first and had a double slim latte on ghiaccio with Amaretto and biscotti.

Italians are sensible. Neutrinos travel faster than light when they jump from CERN Geneva to Gran Sasso Italy and they make better and cheaper lattes. You would too if you were an Italian Neutrino working for CERN who just passed through a paper stupido cup of espresso americano from one of CERN's autocuppa machinas. But Slim in Italia, non subis est.

The LHC is all about human ambition and imagination like other extreme sports. With no more Everests to climb, there's the power of the surreal to conquer. Build a new fantastic Everest and climb it. And take the world with you.

Except the Maya didn't bring an end to the Long Count and all Long Counts, but CERN could, on or before December 21, 2012. Or after, if the Maya got it wrong. Time at CERN might be wrong too measured in bizarre units of 1 trillion collision events, but interesting as a proof of elastic time that might be real. So how many more Inverse Femtobarns to go you guys?


Back To Square One 

The Maya would be impressed with the magic of the LHC.
Is this your temple? What are you doing? You don't know yet!

In the old Mayan days, the stars told them. Outside on a clear night in Spacetime.

LHC Rockets Into Big Bang Space

Alan Gillis Reports As usual CERN physicists at the Large Hadron Collider have been excited by finding nothing yet. That's months after the big media event March 30, 2010 for the first proton collisions at 7 Tera (or trillion) Electron Volts that smashed a few thousand protons. Like 10,000 CERN mechanics starting your new car and how-about-that bonus puffs of proton smoke out the exhaust. Not the full power perfectly safe 7 TeV proton collider from hell we were led to expect from CERN PR. Or the 14 TeV fire-breathing dragon delayed to 2013 because of safety issues and the need for a year's worth of further repairs and upgrades, after the LHC crashed in a spectacular $40 Million accident back in 2008.

Suddenly all that's changed. From the purring collider slowly reving up in CERN's 27 km garage, there's more bang per buck from the $10 Billion LHC. From protons as fuel CERN jumps to the heavy ion run, from say an octane rating of 1.0 for protons, the new heavy lead fuel delivers a whopping 82.0 octane (82 protons in each heavy ion) and the LHC smashes all records for power.

Lead ions are now colliding at the LHC since November 7 and will continue for a month through December 6, 2010. A look back at this year's LHC performance improvements and data highlights shows what a slow slog it's been. Lead ion collisions could radically change all that before it's back to protons and repeat the ion run for another month about this time next year, and then shutdown to rejig the LHC for all of 2012.

The big change? No Big Bang Party for the media.

What we get are some great snapshots of collider fire power. No champagne, no paper hats. Ion collisions more or less in line with expectations. It's of course too early to say what happened exactly, so CERN is still excited by finding nothing yet. Back to square one data analysis but with more excitement. Suddenly we have to wait again for results that could be way more exciting if there's any evidence of New Physics at these colossal new energies. That's the big deal right now: tremendous LHC power equals tremendous excitement. It's roulette on a new wheel and the sky's the limit. Wow!

The first few lucky Pb-Pb collisions happened during the set-up phase before stable and focused lead ion beams, at in ordinary proton power terms, a low for the LHC collision energy of 2.76 TeV recorded at ALICE (bottom image) still far higher than at other ion colliders. Though the LHC is poised to go to the max soon or 7 TeV.

Sounds too low to make a fuss at 2.76 TeV ? Yes and no. What the bigger and heavier lead ions absorb in energy and release is far higher than that. These first heavy hadron or ion collisions rocket the Large Hadron Collider into high orbit, well beyond anything done so far anywhere. According to Fermilab/SLAC's journal SymmetryBreaking, the real energy per lead beam was 287 TeV and so collisions were double that, releasing 574 TeV.

Not exactly or maybe unofficially. CERN hasn't revealed what the highest energy collisions were. SymmetryBreaking bases their numbers at, in proton terms, 3.5 TeV so knock off about half those 287 TeVs per beam until CERN Big Bangs the max and says it's official. Even so CERN achieves a formidable power though why not make it clear even to Fermilab/SLAC? ATLAS shows collisions with stable beams at whatever TeV. At CMS, well pick a number. CERN has kept us guessing before during other earlier (modest as it turns out) LHC milestones. It's the simplified CERN PR approach to success: We did it! (Not at 1/400,000 of what we wanted.)

Should get the 574 TeV full monty later this year. In 2013 in any case with a fully amped LHC or 14 TeV proton energies, lead ion collisions will be around double 574 TeV, or 1148 TeV. Even so each ion today packs an unbelievable punch.

The applied LHC energy and acceleration to very very near light speed, makes each heavy ion much heavier and enormously powerful. A beam of these ions can bore through say a dozen meters of solid stainless steel, producing a small peephole big enough to see through to the other side. And when beams collide?

A Swallow Does Not A Summer Make

First result: We're still here but how long will that last? CERN has only started the big adventure into the unknown with a modest display of heavy ion collisions. What we do have before the evidence is in, is apparently what physicists are calling an ion furnace where the spectacular heat of heavy ion collisions is so great as to dwarf the core temperature of our own sun, and produce a new state of matter a 100,000 times hotter than inside the sun, an undifferentiated absolutely slippery state where particles melt into a new Quark-Gluon Soup. It could be called the ultimate plasma state of matter that physicists think formed in the blink of an eye after the Big Bang. Though apparently not a CERN first or second. Recently re-analyzed data shows Quark-Gluon Plasma was produced at much lower energies at about 0.9 TeV in proton terms during gold ion collisions at RHIC. That's another but much smaller low power collider, the Relativistic Heavy Ion Collider at Brookhaven National Labs.

The LHC ion run discussed in SymmetryBreaking is shooting for much higher power or effectively 14.7 x RHIC and temperatures double RHIC's or 500,000 times the core temperature of the sun. And maybe double that to a million times hotter in 2013.

The Known Unknown And The Unknown Unknown

Unofficially CERN thinks they've nailed the Soup Theory and should be able to produce their own data to support it sometime in the future, if there is still a CERN around in a new altered reality being engineered by CERN now. The more collisions coming at these and way higher energies, the more data for research but also more risks of producing the unknown or some expected and maybe dangerous particles or collider objects like Micro Black Holes and Strangelets that if metastable will affect ordinary matter or even destroy it and the planet.

Then there is always the unexpected in any new experiment and if you believe CERN they're hoping for the unexpected too. Anything would be good it seems. Nothing can be bad, as Dr Fabiola Gianotti, team leader of 3,000 scientists at ATLAS implied recently in The New York Times:


“We have been waiting so long,” she said. “Only good and beautiful things are coming."

The problem is even if CERN gets bragging rights on more and more collisions at higher and higher and higher TeV energies thanks to greater to spectacular luminosities still years away, even without apparent damage to the collider and the world, safety is not assured by any means. For one thing particles ejected from collisions at other colliders are not all contained and some escape. At much higher LHC energies so could dangerous collider objects. Detected or not they might or might not decay harmlessly outside the LHC. If stable they could slowly grow over months and decades or who knows how long and when big enough, then we'll see the threat without the need to agree on theories and complex and mesmerizing data, too late to do anything about a matter destroying object in CERN's big backyard chomping on Geneva and threatening the earth or maybe popping out into space and destroying the moon. It's speculative but what about "Only good and beautiful things are coming."?

The LHC Gateway

It's Reality Sci-Fi. We don't know what the LHC can do and we don't know if disaster will strike. We do have the gateway, a very real $10 Billion experiment. Besides that all we have are a few theories on safety and some reasonable assurances from other low power collider experiments plus some preliminary and minimal results from the LHC. And a lot of don't worry PR from CERN to convince us that the LHC is a perfectly safe Dream Machine that will one day unlock the secrets of matter and the cosmos.

Not perfectly safe yet. What's not being yodeled by the Happy CERN Wanderers a stone's throw from Ja! de Alps, is the very real need for big time upgrades to make the LHC safe beyond the $35 million for the 2012 shutdown and fix, like another $1 to $2 Billion extra to protect the LHC from its own mounting radiation damage (another problem largely ignored by CERN when the LHC was designed and built, like those other problems of poor quality control of the busbars and poor design of the Quench Protection System that both caused the $40 Million 2008 catastrophic failure of the LHC that still needs that $35 Million in 2012 for repairs and upgrades to take a full year to go to a safe 14 TeV).

CERN's lederhosen are down around their knees but they're still not embarrassed in public, because there's no CERN Press Release on that, so no CERN butt showing on the cover of the Rolling Stone.

Yet the sexy LHC has another surprise in its gigantic PR closet. This one better on the accordion and ump-pa-pa if money and beer are no object, but these are hard times. Is $10-12 Billion enough and a Billion more for operations per year for the new already super expensive (so far empty) frontier of High Energy Physics? Probably, actually certainly not, but not in print please. Shhhh we need the PR first, danke. Then comes the shiny new VLHC with something like the mind-boggling power of the abandoned Texas SSC, the Superconducting Super Collider now recycled into a perfectly safe (no PR intended) hole in the ground. What a collider that would have been, a ring 50 km around almost big enough for Dallas? What a terrible blow to particle physics. No wonder CERN has so tenacious a hold on its Ring of Power.

VLHC Anyone?

We still don't know if we'll get any mindbending results from this LHC and will in any case have to go higher to a galaxy very far away to give particle physicists another shot at SSC glory. Why not a souped-up version of the LHC or the Very Large Hadron Collider? Another $X Billion or more? Sure for 33 TeV. CERN has been betting on this upgrade before LHC construction ended, looking 10 years down the road, now 20 after all the Big Bang headaches. Had a big quiet meeting about it in Malta recently. In for a proton, in for a Bigger Bang. But first ramp up the PR research. Develop info mazes where journalists will fear to tread. Don't say needy deserving physicists and poor unhappy half-finished VLHC. Start with Wunderbar Collisions of course. With important spinoffs for BMW and Mercedes in CERN's other bumper-to-bumper network, no better not. Life Ja! is not easy in der Furorbunker, sorry the VLHC Group Think Tank where wistfully Colliders Are Forever.

If all were well at CERN maybe we wouldn't mind being kidded by CERN PR. Might enjoy the thrill of the promised unknown while duped into serenity. Problem is a great deal of effort expended on CERN security and safety is largely from the clattering of keyboards at CERN PR trying to get that just right. There are of course machine safety systems aplenty and they can fail as we've seen in 2008. In the real world at CERN we can only hope that the unsung heros of the Maintenance Department and when all else fails the 2 man teams of Pompiers, can provide safety on the fly as they stand between a rock and a hard place, a stone's throw from Geneva.

The other sort of safety is hard science, but safety papers and arguments regarding experiments are sparse and theoretical and some need revision as there are internal inconsistencies and errors. Other studies are missing. Subsequent new theories and research that bear on possible LHC results have yet to be fully considered. Worse, there are also other possible spooky interpretations of CERN's House of Cards. Here's another rare insight from the CERN shop floor, again from Dennis Overbye's recent article in The New York Times:
In interviews recently, scientists and managers said that they had been too eager to get the collider running at full power in 2008. “In perspective, we may say we started too ambitious,” said Lucio Rossi, a superconductivity expert who joined CERN from the University of Milan in 2001. One reason, in his opinion, was arrogance.

A Brief History Of The End Of The World

Start here. While we're waiting for new revelations there's a backlog of papers on the curious evolution of the hard science of safety at the LHC. There's Professor Eric E Johnson's monumental and entertaining study of CERN's soft safety mythos and other mystifications from a legal perspective in "The Black Hole Case: The Injunction Against the End of the World."

A summary and further comments by Professor Johnson and some CERN feedback like Why didn't you talk to us first? in New Scientist; Professor Johnson interviewed on World Radio Switzerland; these and several major articles on Johnson's 90 page paper by journalists like Kevin Hassett of Bloomberg, can all be found via links from Johnson's blog, Pixelization.

Then there are dozens of my articles here in The Science of Conundrums, NewsHammer and elsewhere, and many of them syndicated in the Chicago Sun-Times and USA Today that cover new and similar shakey ground under the LHC going back to 2007. Here's a sardonic favorite from the Alan Gillis archives: "The Black Hand Of Dr Cern". Wacky? Well compare this with Professor Johnson's coverage of bizarre safety assurances by CERN's LSAG and SPC, in section IV.G "The Rise of Certitude" pdf pages 31 to 34 from the above link to "The Black Hole Case...".

Strangelets Yes We Have No Strangelets

If it can't get any more self-serving at CERN, well there's more sauce from the gander, in Eric Penrose's recent startling and comprehensive review of CERN's creative cookie cutting strategy on Strangelets, "How CERN’s Documents Contradict its own Safety Assurances: Plans for "Strangelet" Detection at the LHC" at http://heavyionalert.org/

CERN minimizes risks of whatever sort, but Strangelet dangers are here now if uncertain. Strangelet production starts with Quark-Gluon Plasma discussed above and likely produced in this first ion run. With more and more lead ions colliding at the LHC at higher and higher luminosities now through December 6, Strangelets are the new frontier in planet disaster and Micro Black Holes might show up as well. No, says CERN and CERN might be right.

But if CERN's credibility is an issue and it is, why should we believe what CERN says? As far as Strangelets go, why build a separate super CASTOR detector specifically to detect Strangelets from collisions at the CMS experiment? To detect Centauros with CASTOR of course because CERN says Strangelets won't be produced but Centauros might be. Then why look for Strangelets? The sky cannot fall down but maybe it will. It's as goofy as that and deadly serious. Yet science journalist Alan Boyle in CosmicLog gives CERN a sympathetic hearing:


The CASTOR researchers themselves voice no concern about a catastrophe. Instead, they see their experiment as a straightforward effort to find evidence of exotic phenomena previously associated with cosmic-ray collisions, including centauros and strangelets. The doomsday connection is being made by the doomsayers themselves ... plus maybe a few physicists exercising their imagination.

CASTOR researchers work for CERN like BP researchers work for BP. Doomsayers work for both but won't risk being censured or banished by speaking up in public. We all wait for a maybe/maybe not accident to happen and that includes journalists. Doom scenarious don't materialize out of thin air as we find out later from journalists when it's too late. There are causes and dismissing all risk or saying nothing starts the ball rolling. Before knocking doomsayers there is perhaps a deeper pathological syndrome attached to saying or doing nothing in some cases, a conscious or unconscious death wish that gets doomsayers talking too.

If that's unfair then we can go back to the usual argument used again by CERN outlined in Boyle's article for the shifting ground under CASTOR: That was then and this is now. CASTOR was designed a long time ago during the interminable LHC time warp or a few years back in real time. In terms of physics as understood then. To sum that up, Strangelets are not expected due to recent data analysis from RHIC's heavy ion research. "The theoreticians are changing their minds." said Yasar Onel who works on CASTOR, as quoted by Boyle.

CERN Logic: That Was Then. So What?

Fine, but think that through. CERN was building a detector for Strangelets that CERN thought could be produced at CMS then, that clearly demonstrates a disregard for safety at the LHC. CERN was going ahead regardless of consequences.

What has changed is not CERN attitudes to safety but the theoretical nature of Strangelets, from hints at RHIC. So CERN is off the hook for Strangelet production if CERN is right about RHIC data, that Strangelets shouldn't form in very hot heavy ion collisions at the LHC. But what happens when QGP cools and decays?

How are any of these twists and turns down the CERN maze reassuring?

CERN didn't understand hypothetical Strangelets but now they do? Uncertainties then in physics, but not these uncertainties now? How can we be confident about the present state of theoretical knowledge when according to CERN or any physicists, physics is a science in progress? What can we know for certain? That theories change, that the sometimes dangerous unknown can rear its head? Doesn't this happen daily in all the sciences?

Collider Good. Results Good.

Not at CERN it seems. At the LHC no matter what happens we're safe from hypothetical knowns and unknowns. This at the world's biggest and most powerful machine, the biggest experiment ever, engineered for a very different scale of cosmic discoveries forced into being by colossal LHC energies, with no possible planet shattering impact or local threat? No chance? That's PR/BS. CERN has bet $10 Billion on a scaled down Big Bang. This is an event that physicists say can produce some of the expected hypothetical and maybe the unknown at the LHC. That's why CERN built the LHC to find out what will happen at the LHC.

The amazing collider and its cleverly engineered bigger and better firestorm also has an infectious back-reaction. CERN's heady confidence in the machine spills over into the unknown results that can't be bad. Collider good, results good.

If tiny Strangelets and tiny Black Holes (expected by CERN but also denied by CERN) shoot out of the LHC, will they ever be detected? Even if they are, what can stop them from devoring and transforming matter into more and more Strange Matter and bigger and bigger Black Holes if they are merely detected? CERN has no magic box to collect them and no charms and chains to rattle to spook them out of existance and certainly no anti-mBH or anti-Strangelets to sprinkle on them to destroy them. There's only mumbo-jumbo for planet destroying collider objects that might surface years later, though I suppose CERN's PR department is up to the challenge.

You might read this yet in the CERN The Bulletin: Strangelets and mBH are keeping CERN physicists awake all night . . . but scientists have taken up the challenge and are ready for the future.

Other Headaches In Particle Physics

Another piece of ATLAS. Where do neutrinos fit in? Not in the Standard Model. Nor whatever happened to antimatter, when the Big Bang supposedly released equal amounts of matter and antimatter, which should have annihilated each other, leaving only energy behind. Why does the Universe obviously prefer matter? And why isn't the Universe homogeneous everywhere like a field of stars without galaxies if it expanded out from an orange-sized ball? Why is it expanding when gravity would tend to stop expansion, indeed reverse the Big Bang into the Big Crunch? Well there are theories and theories about all this. At the LHC they've got a long list of questions about theories and they think some are bound to be answered from data they expect and maybe don't expect.

Meanwhile Astrophysics seems to be overtaking Physics and Particle Physics. It's like the revenge of Astrophysics. With only 4% of the matter of the Universe accounted for, astrophysicists say, the rest invisible, maybe there wasn't a Big Bang after all? Anyway 96% of the Universe right there, doesn't fit into the Standard Model. It's only a bit of background microwave energy Science leans on and some expansion, the red shift well noted, that is the proof for the Big Bang theory. Besides, where did the orange come from? While particle physicists are attending endless meetings at CERN, the impossible is happening all around us in space.

You might remember black holes being popular as a simple theory of matter accumulating into an unimaginably dense body so small it might appear like a massless black hole, sucking up more matter and energy. After many years of uncertainty, some have been found inside galaxies thanks to space-based telescopes like the Hubble and recently Spitzer and Chandra. But then the theory suggests they're unstoppable and would eventually absorb the galaxies they're in and there are still perhaps a 100 billion or more galaxies and no sign of any big trouble. Then a spectacular find, a black hole from a galaxy 3C321, the death star galaxy in the news last December, erupting a jet of radiation 850,000 light years long, striking another smaller galaxy about 20,000 light years away, and 1.4 billion light years from us.

A black hole releasing considerable energy, except perhaps into some other fantastic dimension, was entirely unpredicted. Only some suggestions of black holes possibly exploding, and Stephen Hawking's 1974 theory that a black hole could decay via a thermal radiation created by the black hole itself, slowly leaking (still unconfirmed) Hawking radiation. If 3C321 can happen, then what of unexpected results at the LHC?

Now of course someone at NASA or somewhere is bound to post a patch for black hole theory and dine on the celebrity status for a lifetime, like all scientists dream of. But how would you patch Geneva, Mount Blanc and a lot of great ski resorts popular with grad students, postdocs and trendy physicists at CERN, patch that and all of Switzerland and a good chunk of France, say to Marseilles?

Some are worried over at CERN. Not officially, like don't bite the hand that feeds you. There's an unusually smooth PR operation going on at CERN to keep things humming, even professional seminars on how to handle the media in Spotlight on the media. Mind you everything is above board and transparent with terrific open access to most anything going on at CERN. You won't find any conspiracy or conspiracy theorists. If you dig hard enough into private online blogs, you'll discover a few cool and amused dissenters. There's edgy good fun in cold war rivals, ATLAS and CMS, each calling the other the enemy. And gallows humor, like the Doomsday Machine. All they need is a Dr Strangelove. Don't worry about black holes. There's this special radiation.

And if you've still got a headache, be brave. Take one LHC with a little superfluid helium before bedtime and you should be fine in the morning.

Physics' Big Headache Or Why Build The LHC

Testing thousands of lead tungstate crystals for ECal. The problem is the Standard Model in Physics which seeks to unify the weak force, the strong force and the electromagnetic force, 3 of the 4 major forces, gravity left out because it has so little effect on the subatomic scale, particle physicists think. Anyway they're obliged to, because gravity refuses to fit in.

What they've got since the 1960's is chunks of theories that seem to work fine as parts of the puzzle, but at the very least other pieces are missing. And if they don't find them, then the Standard Model might be no better than a Ptolemaic theory of sun and planets going around the earth.

The Standard Model is messy too. It's not simple and elegant like Einstein and Newton. It won't give us values for particles. They have to be arrived at through experiments with colliders like the LHC. In the breakthrough Electroweak Theory, uniting both electromagnetism and the weak force, add any value like mass to these equations and they don't work. Then all particles have no mass. And they should all travel at the speed of light. This is the absurd reality of particle physics. But it won a Nobel Prize at CERN, so experimentally confirmed in part. What are we doing then, imagining the Universe? Enough to give any physicist some sleepless nights and a cosmic hangover in the morning.

But physicists cling to the Standard Model because they don't have anything else except stranger theories without a shred of experimental proof. All the Standard Model needs is some improvement, like a new theory to confer mass on particles from the outside. Enter the theoretical Higgs boson. At CERN they're hoping to find it with the LHC, or maybe create a Higgs field from a hadron fireball. Gone are the days of simple atom smashing. CERN actually wants to simulate on a small scale with colossal energies, what conditions were like 13.7 billion years ago, when there must have been a Higgs field, a billionth of a second after the Big Bang.

To do so a stone's throw from the Geneva Airport is taking an incalculable and unnecessary risk.

Who wants a theoretically dangerous anything in your backyard? Maybe if there were some real benefit, but is anyone really the wiser or better off when a $10 billion theory is confirmed or denied, and of interest only to a small group of physicists?

It's about as pointless an exercise as the Tower of Babel. Granted it's way more sexy. Science Porn, Boing Boing calls it.

The Logic Of Science

On the left, the ultimate portable atomic clock, the size of a grain of rice from NIST and DARPA, 2004. Works using a tiny laser. Accurate for 300 years. A bit of overkill. Do we really need these in cell phones to come? Whether we want these gizmos or not is irrelevant. Some corporation will decide to manufacture them and soon they'll be everywhere. It's the logic of the age we live in. It's also the logic of Science. Actually a simple definition of Science, apart from the Latin root To Know, from the earlier verb To Cut, is the application of logic to all phenomena. That's how Science started in the mists of time when people perceived an orderly pattern to things that had a logic to it. That's also Science's Central Dogma, that the Universe is logical. On this one assumption everything rests. If Science ever hits a brick wall, it will be the discovery of something beyond logic. But Scientists are confident that will never happen, although there are many baffling gaps in their knowledge, the manufacturing of logical theories to cover them is almost as good as having the knowledge they lack, a working hypothesis.

It's these theories that scientists keep on testing, whether it's smashing atoms or toying with genetics. This is Big Science, the biggest game of all time. Of course, Science's parameters are those of the known physical Universe. What they expect to find and measure has to be physical, since after all they use physical instruments. But what if there are Non-physical Universes informing this one or even shaping it? Then they'll never be able to find out for certain if the Universe is logical or not.

Somewhere in the early 20th century Science split off entirely from Art. Now it's all theory and experiment, without a thought for consequences. It's aim like Art's was a certain amount of pleasure and usefulness, like the compass rose above. Now it's an endless stream of data that even overwhelms its specialist fields, and specialists can't keep up, where now a chemist and a physicist haven't got much in common and can't understand each other's work. It's becoming all rather dehumanizing. But we go on.

The latest big thing in Physics, another theory is theoretically we have Dark Matter and Dark Energy, surmised but not yet detected. Well, there are deficiencies in the Big Bang theory. To satisfy them, the known Universe of matter and energy now accounts for only 4% of the total Universe, the rest or 96%, is this unknown dark matter and dark energy we haven't detected. And Antimatter might exist as stars and galaxies where there is no ordinary matter, which would annilate it. Antiparticles have been found, but no Antimatter, though CERN and later Fermilab with CERN's assistance actually created a few atoms of antihydrogen. It's superhot and with no way to contain it, it's readily annihilated in 10 seconds, releasing 100% of its energy and ordinary hydrogen's in contact with it. 100% energy efficient whereas a hydrogen bomb is only 7%. More dreams of an endless supply of energy, except it's way too expensive, at least $25 million a gram.

Anyway, we're in an age of endless speculation and experimentation. The effect on civilization is destabilizing. Some of this Science trickles down to us and now we're living with machines instead of friends and family. With cars instead of horses, with bulbs instead of candles. Are we better off?

Yet we're still trying to get to the bottom of this Universe. It's one thing to daydream. We all do it even those who are PhD deficient. Another to test any and all theories endlessly. But the real worry is Science's destructive experiments and applications of destructive research which eventually affect us all. From one bomb at Los Alamos to a giant nuclear arsenal and a thousand nuclear reactors and no way to safely dispose of them. While we've got our hands full of problems dumped on us by Science that Science is not addressing, a new era of Big Science is dawning. Genetic manipulation and Nuclear Fusion and Super Colliders like CERN's LHC, due to start up in 2008. What's really going to happen when lead nuclei are smashed together in the LHC at super colossal energies never before attempted? Collisions at nearly twice the speed of light? This isn't atom smashing anymore, this is a new type of Fusion Reaction. Even some physicists are demurring. It could be the end of the world.
