摘要：

We have investigated phenomenological implications on the neutrino flavor mixings in the S-3L X S-R symmetric mass matrices including symmetry breaking terms. We have shown how to get the large mixing angle MSW solution, sin(2)2 theta. = 0.65-0.97 and Delta m.(2) = 10(-5)-10(-4)eV(2), in this model. It is found that the structure of the lepton mass matrix in our model is stable against radiative corrections although the model leads to nearly degenerate neutrinos. (C) 2000 Elsevier Science B.V.
