Permutation symmetries and the fermion mass matrix

We consider SU(2) x U(1) gauge models with an additional global symmetry of S/sub n/ type. In particular, we study S/sub 4/ symmetry for a six-quark--six-lepton standard model. We find that the Kobayashi-Maskawa matrix is completely determined and the mass of the t quark is predicted. Some of the results persist in S/sub n/ applied to n families. Restrictions on neutrino masses and mixings are given. Implications of CP and flavor nonconservation that arise in the neutral-Higgs-boson sector are discussed.
