Higgs boson

Show Summary Details

Quick Reference

A spin-zero particle with a nonzero mass, predicted by Peter Higgs (1929–  ) and others to exist in certain gauge theories, in particular in electroweak theory. The Higgs boson has not yet been found but it is thought likely that it will be found by larger accelerators in the next few years, especially since other associated features of the theory, including W and Z bosons, have been found. In the standard model there is only one Higgs boson but in the minimal supersymmetric standard model it is predicted that there should be five Higgs bosons, two of which are electrically charged. See also Goldstone's theorem.
