The '''Standard Model''' of [[Particle|particle]] physics is a [[quantum field theory]] that explains [[Electromagnetism|electromagnetism]], [[Strong nuclear force|strong]] and [[Weak interaction|weak]] [[Nuclear|nuclear]] interactions in a unified framework.  It is a non-[[abelian]] gauge theory with the gauge [[Group (mathematics)|group]] [[Unitary group|SU(3)×SU(2)×U(1)]].

It was formulated in the 1970s and has withstood all experimental tests. It has only been modified by adding mass to the electron neutrino. Physicists have just announced the discovery of its most enigmatic prediction, the [[Higgs boson]].
