They have found a bump in their data that might be the long-sought Higgs boson. Read more:

In the entry 2012 Feb 20 – World explanation theory the last paragraph read:
After “his” Higgs data were analysed, US researcher Roser wants to announce them at the beginning of March on the Moriond conference in the Italian place La Thuile to the specialist world.

Today now I read an article that brings information about the result of this analysis and here are some excerpts:

 

After 40 years, more evidence is being reported Wednesday that the end of the biggest manhunt in the history of physics might finally be in sight.

Physicists from the Fermi National Accelerator Laboratory in Batavia, Ill., say they have found a bump in their data that might be the long-sought Higgs boson, a hypothesized particle that is responsible for endowing other elementary particles with mass.

The signal, in data collected over the last several years at Fermilab’s Tevatron accelerator, agrees roughly with results announced last December from two independent experimental groups working at the Large Hadron Collider at CERN, the European Organization for Nuclear Research, outside Geneva.

“Based on the current Tevatron data and results compiled through December 2011 by other experiments, this is the strongest hint of the existence of a Higgs boson,” said the report, which will be presented on Wednesday by Wade Fisher of Michigan State University to a physics conference in La Thuile, Italy.

The Higgs boson is the key piece of the Standard Model, an ambitious suite of equations that has ruled the universe of high-energy physics for the last few decades, explaining how three of the four fundamental forces of nature work. But the boson itself has never been observed. The theory describes how it should work and behave but does not predict one of its key attributes, namely its mass.

The Atlas and C.M.S. groups will be trying to combine and reconcile their data in the coming weeks. The Hadron collider, now on winter break, will start up again in April, with protons colliding at four trillion electron volts apiece. CERN has said that the collider will gather enough data this year either to confirm the existence of the Higgs boson or to rule it out forever.

Either outcome, physicists say, will be exciting. If the Higgs does not exist, they will have to come up with a new model of how the universe works. If they do find the Higgs, studying it might give them clues to deeper mysteries the Standard Model does not solve.

The Tevatron, which was the most powerful accelerator in the world for 20 years, shut down last September.
