The Standard Model of Fundamental Particles and Interactions

The Standard Model of particle physics is a quantum field theory that explains electromagnetism, strong and weak nuclear interactions in a unified framework. It is a non-abelian gauge theory with the gauge 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.
