Evidence for the Higgs Boson?
CERN - In a scientific seminar that has been broadcast worldwide today, the two large-scale particle physics experiments ATLAS and CMS at CERN, the European Organization for Nuclear Research in Geneva, presented the latest results in their search for the Higgs boson. Three RWTH institutes are participating in the experiments. The experiments investigate the reactions triggered by the collision of high-energy protons in the Large Hadron Collider (LHC). At a mass of approx. GeV/c2 (giga electron volt), both experiments have gathered evidence for a new particle, which might be the long searched-for Higgs boson. By now it can be ruled out that the observed events are due to statistical fluctuations of the background: in both experiments the probability of such an explanation is less than one in a million. Evidence for the new boson is provided through the decay of it into two photons and two Z bosons. There is some evidence that the observed particle is indeed the Higgs boson.
