| heal.abstract | We discuss renormalization effects on neutrino masses and mixing angles in a supersymmetric string-inspired SU(4)xSU(2)(L)xSU(2)(R)xU(1)(X) model, with matter in fundamental and antisymmetric tensor representations and singlet Higgs fields charged under the anomalous U(1)(X) family symmetry. The quark, lepton and neutrino Yukawa matrices are distinguished by different Clebsch-Gordan coefficients. The presence of a second U(1)(X) breaking singlet with fractional charge allows a more realistic, hierarchical light neutrino mass spectrum with bi-large mixing. By numerical investigation we find a region in the model parameter space where the neutrino mass-squared differences and mixing angles at low energy are consistent with experimental data. | en |
