摘要：

It was recently shown by the authors that the Fritzsch Ansatz for the quark mass matrices prescribed at the supersymmetric grand unified scale is compatible with a moderately heavy top quark (m(t) congruent-to 120-150 GeV). Here we extend the Ansatz to incorporate the charged leptons and the neutrinos. It is found that the nu(e)-nu(mu) mixing angle is small and consistent with the MSW solution of the solar neutrino puzzle. Furthermore, the model predicts observable nu(mu)-nu(tau) oscillations with sin(2)2theta(mutau) congruent-to 0.1 and nu(tau) mass in the 1-3 eV range.
