In a model where quark and lepton masses and family-mixings are caused not by a variety of Yukawa couplingsyij(i,j=1, 2, 3: family indices) with one vacuum expectation value (VEV)ν=〈φL0〉0, but by a variety of VEV’s of a U(3)-family nonet Higgs bosonφL,vij=〈φLi0j〉0, with a single coupling constant, the following problems are investigated: what constraints on the Higgs potential are imposed in order to provide realistic quark and lepton mass spectra and mixings and what constraints on the Higgs…
