The Higgs boson is an elementary particle associated with the Higgs field, which in the Standard Model of particle physics gives mass to other fundamental particles. The existence of the field and its particle was proposed in 1964 by Peter Higgs and, independently, by Francois Englert and Robert Brout, and by other physicists. After decades of searching, the ATLAS and CMS experiments at CERN's Large Hadron Collider announced the discovery of a new particle with a mass of about 125 gigaelectronvolts in July 2012. Its properties matched those predicted for the Higgs boson. Englert and Higgs shared the 2013 Nobel Prize in Physics, and the discovery completed the Standard Model.
