libero Posted July 4, 2012 Posted July 4, 2012 (edited) Sheldon will be happy Cern scientists reporting from the Large Hadron Collider (LHC) have claimed the discovery of a new particle consistent with the Higgs boson. The particle has been the subject of a 45-year hunt to explain how matter attains its mass. Both of the Higgs boson-hunting experiments at the LHC see a level of certainty in their data worthy of a "discovery". More work will be needed to be certain that what they see is a Higgs, however. The results announced at Cern, home of the LHC in Geneva, were met with loud applause and cheering. Peter Higgs, after whom the particle is named, wiped a tear from his eye as the teams finished their presentations in the Cern auditorium. Peter Higgs joined three of the six theoreticians who first predicted the Higgs at the conference "I would like to add my congratulations to everyone involved in this achievement," he added later. "It's really an incredible thing that it's happened in my lifetime." The CMS team claimed they had seen a "bump" in their data corresponding to a particle weighing in at 125.3 gigaelectronvolts (GeV) - about 133 times heavier than the proton at the heart of every atom. They claimed that by combining two data sets, they had attained a confidence level just at the "five-sigma" point - about a one-in-3.5 million chance that the signal they see would appear if there were no Higgs particle. However, a full combination of the CMS data brings that number just back to 4.9 sigma - a one-in-2 million chance. Joe Incandela, spokesman for CMS, was unequivocal: "The results are preliminary but the five-sigma signal at around 125 GeV we're seeing is dramatic. This is indeed a new particle," he told the Geneva meeting. Atlas results were even more promising, at a slightly higher mass: "We observe in our data clear signs of a new particle, at the level of five sigma, in the mass region around 126 GeV," said Fabiola Gianotti, spokeswoman for the Atlas experiment at the LHC.
