Race For the "God Particle" Heats Up 397

SpuriousLogic writes "CERN is losing ground rapidly in the race to discover the elusive Higgs boson, its American rival claims. Fermilab say the odds of their Tevatron accelerator finding it first are now 50-50 at worst, and up to 96% at best. CERN's Lyn Evans admitted the accident which will halt the $7B Large Hadron Collider until September may cost them one of the biggest prizes in physics."

      What data are they lacking? The math and physics from other experiments that suggest that the Higgs Boson exists, along with a lot of details about it? Or the fact that it is by far the simplest solution to a number of phenomenon? Remember, much more often than not, the simplest solution that fits the math tends to point to the correct answer.

      Oh wait. They aren't lacking those.

      • Addendum,

        this could also be bad journalism, they may simply mean demonstrating that it does or does not exist.

        Either way, probabilities can be given. The former situation (proving it does exist) has a more rough probability since it it would use similar, but nonetheless different circumstance, while the latter (proving that it does or doesn't) exist is requires less external data, and is thus a less rough calculation

        We have a good idea of what sort of range its mass is likely to have but that's not certain. Some physicists are even hoping that it won't be found, pointing to a much larger mass and interesting new physics to explore.

      Anyway theres pretty reasonable indirect evidence for the Higgs, lets just say to make all our measurements consistant, it would be nice if a fundamental scalar existed around 115 GeV. And it would be even nicer if it generated all the masses in the Standard Module while it was at it. There is certainly enough to have a reasonable Bayesian prior.

      The great thing about scientific theory - real scientific theory - is that is has predictive capabilities. Theory predicts that the Higgs exists. If the theory is correct, they feel that their experiment has a 50% to 96% chance of finding it.

      And if they don't find it, it would actually be a bigger deal than if they do. It means something was off either in the experiment or the theory, and that means it's back to square one!

    • The LHC will be to give a definitive answer to the question as to whether the Higgs Boson can exist. the LHC will pretty much give a clear yes or no answer, its not going to be indeterminate. They have create the conditions where they know that one will have to appear, with certainty that if they cannot produce it, it will indicate that Higgs is likely impossible to exist. This is an important moment for verifying the Standard Model and has will be one of the greatest discoveries lately.

    • Well, if the theory includes any sort of number of those particles that would be required for it to fit the problem that the theory was trying to solve, and you have other theories that fit with less things observed previously, then no, it's fairly sensible to quote the odds.

    • Even so, 50-50 to 96% is a pretty good spread of odds.

      What they mean (yes, I'm on CDF, and beginning my own segment of a Higgs search analysis), is that there is a 50/50 chance that the Tevatron will have acquired sufficient data for us to be sensitive to a Standard Model Higgs at reasonable mass ranges (115 - maybe 300 GeV/c^2). Thus, if it exists (the SM Higgs specifically) we'll be able to tell it is there, and if it does not exist, we'll be able to say with a high level of confidence that it is not there.

      To discover the Higgs, we must show that given a theory without the Higgs, our data would only occur 1 in 2 million times we did an experiment like this, (5 sigma significance, standard for particle discovery) and of course the the difference in the data is consistent with a Higgs.

      To exclude the Higgs in a certain mass range, we must show the opposite: if there were a Higgs, our data would only occur some very small percentage of the time (I can't remember the exact significance, but it is less stringent than discovery, again standard).

      LEP already excluded masses below 114 GeV/c^2, and the Tevatron has excluded a small mass range around 160 or 170 GeV/c^2.

      However, all that said, I disagree with the apparently official Fermilab line (50/50). We have a small chance of excluding all the available mass ranges, but the amount of data needed to go from excluding it if its not there to discovering it if it is there is huge. We would need several times as much data as we will have unless we keep running for quite a bit longer. Maybe we can get a chunk of the gov't stimulus package? ;)

      Without any data to base your odds on, you're just making some shit up. Not only is their level of precision low, but there is zero confidence.

      Quite the contrary, sir, and I do somewhat resent remarks like these, although I understand they were made in haste in your frenzy to get first post. We have a tremendous amount of data, and we have theories that describe exactly what we're looking for. It's almost just a statistical game now. Our level of precision is in fact quite high (although not as high as is achievable at a lepton collider), and as I said above, we have excluded some potential Higgs masses to a high level of confidence.

    • A few decades of particle physics experiments adds up to no data? That's pretty harsh.

      Its very important for us to improve our data base and understanding of physics. While for some it may seem abstract it is often the case that data which at first seems to be inconsequential and a curiosity plays a critical role in developing some new technology. Understanding how atoms work for instance, gave rise to many new inventions that were probably not anticipated originally, such as understanding how transistors work.

      Science is very important to solving our economic problems and collecting data allows science to better understand the universe and be able to develop better technologies.

Although, to be fair, most of the alternative theories are very similar at the end of the day, just with different decay and production signatures and such, so it might not be such a huge deal.
