摘要
In the simplest model of horizontal U(1) symmetry with one singlet added to the supersymmetric standard model, we systematically reconstruct quark mass matrices from the low-energy data to prove that there are only two mass matrices found by Binetruy et at. The same U(1) symmetry constrains the hierarchical structure of L-violating couplings, from which we build radiative neutrino mass matrices accommodating the solar and hot dark matter neutrino masses and mixing. We find a few patterns of acceptable charged lepton and neutrino mass matrices, most of which are consistent with large tan beta similar or equal to m(t)/m(b) only.
