LHC Prepares Marathon Higgs Hunt
gbrumfiel writes "Physicists at the Large Hadron Collider are preparing to run the collider until the end of 2012 in the hopes of finding the Higgs particle, part of the mechanism that endows other particles with mass. The machine was originally supposed to stop in 2011 for a year long upgrade, but scientists now think they can find the Higgs if they run for longer. 'If we stop the machine with 3,000 people apiece in the experiments waiting for data, there is no way we could get home at night without having slashed tyres on our cars,' says Sergio Bertolucci, CERN's director for research and computing."
That's so mean.
"If we stop the machine with 3,000 people apiece in the experiments"
Woah woah woah, I think someone got confused about what they're meant to be colliding here. I don't think smashing grad students is the answer.
No kidding!!! What do you say at this point?
"Physicists at the Large Hadron Collider are preparing to run the collider until the end of 2012" Thanks captain obvious. I'm not a moron, I know they won't be running it AFTER the world ends.
Not saying it does or doesn't, but at what point would they would decide to quit searching it for it?
Probably at the point at which they traced, with sufficient statistics, the whole energy range where the Higgs may be found, and didn't find a trace of it.
The Tao of math: The numbers you can count are not the real numbers.
"Physicists at the Large Hadron Collider [CC] are preparing to run the collider until the end, in 2012.
Set your phasers on "funky"!
A few years, maybe 3-5, should be enough to rule out the Higgs over the entire range of masses it could have. From what I gather, since the percentages of some processes no longer add up to 100 at LHC energies, something has to be there. It's theoretically possible this something could be heavy enough and hard enough to see that the LHC wouldn't find it, but no actual models predict anything that would be invisible at the LHC.
I'm sure some physicists will be actually quite disappointed by finding the Higgs. Although it seems to be required in order for the standard model to be a success, it would actually be quite exciting if it isn't found as it means a whole different paradigm for mass is at work in the real universe. I believe for example I've seen Brian Cox say that he would be more excited by a lack of a Higgs than by finding it, although the politicians who fund these things might not be too happy I suppose.
The main reason that there is a broad consensus that the Higgs exists is simply that nobody seems able to think of a simpler mechanism through which mass might work.
I do not want your cheap brainburning drugs. They are useless for work. And I am a working man today.
The article stated that a big driver for continuing the search at current energies is that Fermilab is right on their heels and might find the Higgs first if they take a break for a year.
As I see it, the Higgs could fit into one of two energy ranges:
1. A range that the limited LHC and Fermilab can both probe now, with the LHC having some advantage.
2. A range that only the full LHC can reach.
If it falls into the latter, then nobody is discovering the Higgs for a few years until they get the LHC in gear. If it falls into #1, does it REALLY matter that much who finds it first?
If what we care about is the accumulation of knowledge then we should cooperate and not compete here. Retask the LHC for higher energies, and have Fermilab continue to explore the lower-energy space. This way we find the Higgs more quickly as we have two non-redundant operations working on the problem, rather than having one be completely redundant.
Also, who knows what other interesting physics we'll find at the higher LHC design energies, that we're just pushing off for years sticking where we are at now?
Can't the lead authors on the competing 1000-author papers maybe agree to pool their efforts, and settle for first and last on a 2000-author paper instead? :) Then we poor taxpayers footing the bill can at least feel like we're all getting SOMETHING for our money...
The worst-case scenario is finding the Higgs and nothing else. Then we'd be out of jobs.
The main problem is that those experiments suggest that CPT symmetry is broken (or, in non-technical terms, that a reaction with antimatter isn't the same as the same reaction with matter with the opposite charge, time reversed and seen in the mirror). CPT symmetry can be shown to be equivalent to Poincaré invariance, which means that these results challenge not only the standard model, but special relativity itself. Such an extraordinary claim needs really extraordinary evidence, so let's wait for more statistics for now.
