Idea

Besides the forces of electromagnetism and gravity there are two more fundamental gauge fields in the standard model of particle physics.

The weak nuclear force is described by a gauge field with gauge group the special unitary group SU(2)SU(2) (W-boson, Z-boson). It controls aspects of the beta decay.

The strong nuclear force is described by a gauge field with gauge group the special unitary group SU(3)SU(3) (QCD (gluon). It governs the interaction between quarks.
