The Higgs boson or Higgs particle is an elementary particle in the Standard Model of particle physics. The Higgs boson is predicted to exist for theoretical reasons, and may have been detected by experiments at the Large Hadron Collider. If confirmed, this detection would further support the existence of the hypothetical Higgs fieldthe simplest of several proposed mechanisms for the breaking of electroweak symmetry, and the means by which elementary particles acquire mass. The leading explanation is that a field exists that has non-zero strength everywhereeven in otherwise empty spaceand that particles acquire mass when interacting with this so-called Higgs field. If this theory is true, a matching particlethe smallest possible excitation of the Higgs fieldshould also exist and be detectable, providing a crucial test of the theory. Consequently, it has been the target of a long search in particle physics. The Higgs boson is named after Peter Higgs, whoalong with R.
