On July 4, 2012, two collider experiments, CMS (Compact Muon Solenoid) and ATLAS (a toroidal LHC apparatus), at the Large Hadron Collider (LHC) simultaneously announced the discovery of a particle with mass 125 GeV (about 130 times heavier than the proton), which is consistent with the standard-model Higgs boson. The Higgs boson is the final particle to complete the picture of the standard model. It was proposed more than 40 years ago by a number of physicists, including P. W. Higgs, for whom the particle was named. The Higgs boson is the remnant of the so-called Higgs mechanism, which was designed to give masses to fermions and gauge bosons. The discovery of the Higgs boson can further consolidate our understanding of the origin of mass and electroweak symmetry breaking. This is perhaps the most significant discovery of modern particle physics. It will have influence on all theoretical and experimental research in the future.
