" Thus the strong force,which is endowed with eight-dimensional SU(3) symmetry, is mediated by
eight gluons; the field of the weak force, which is endowed with three-dimen-
sional SU(2) symmetry, is mediated by three particles, the W+ W–, and Z
bosons; and the electromagnetic field, which is endowed with one-dimensional
U(1) symmetry, is mediated by a single particle, the photon."
