Exotica
The standard model of particle physics is a Yang-Mills gauge theory with gauge group (a discrete quotient of) . Here the first factor is the gauge group of QCD while the -gauge field is that transmitting what is called the electroweak force.
The name is due to the fact that this gauge field unifies the electromagnetic field and that transmitting the weak nuclear force: the Higgs mechanism induces a spontaneous symmetry breaking of the electroweak field to these two fields. See at electroweak symmetry breaking.
