Lepton flavor violating processes in the bimaximal texture of neutrino mixings

We investigate lepton flavor violation in the framework of the minimal supersymmetric standard model with right-handed neutrinos taking the large mixing angle Mikheyev-Smirnov-Wolfenstein solution in the quasidegenerate and inverse-hierarchical neutrino masses. We predict the branching ratio of mu-->e+gamma and tau-->mu+gamma processes assuming degenerate right-handed Majorana neutrino masses. We find that the branching ratio in the quasidegenerate neutrino mass spectrum is 100 times smaller than the ones in the inverse-hierarchical and hierarchical neutrino spectra. We emphasize that the magnitude of U-e3 is one of the important ingredients to predict BR(mu-->e+gamma). The effect of the deviation from the completely degenerate right-handed Majorana neutrino masses is also estimated. Furtheremore, we examine the S(3L)xS(3R) model, which gives the quasidegenerate neutrino masses, and the Shafi-Tavartkiladze model, which gives the inverse-hierarchical neutrino masses. Both predicted branching ratios of mu-->e+gamma are smaller than the experimental bound.
