An undated handout graphic distributed on July 4, 2012 by the European Organization for Nuclear Research (CERN) in Geneva shows a representation with a zoom effect of traces of traces of a proton-proton collision measured in the Compact Muon Solenoid (CMS) experience in the search for the Higgs boson. Physicists have found a new sub-atomic particle in their search for the Higgs boson, a top CERN scientist said on July 4, 2012. « We have observed a new boson, » said Joe Incandela, spokesman for one of two CERN laboratories working on the quest for the Higgs, the particle that is believed to explain the mystery of mass.
