Neutrino Bimaximal Texture and Lepton Flavor Violation

We investigate the lepton flavor violation in the framework of the MSSM with right-handed neutrinos taking the large mixing angle MSW solution in the quasi-degenerate and the inverse-hierarchical neutrino masses. We predict the branching ratio of μ → e + γ processe assuming the degenerate right-handed Majorana neutrino masses. We find that the branching ratio in the quasi-degenerate neutrino mass spectrum is 100 times smaller than the one in the inverse-hierarchical and the hierarchical neutrino spectra. We emphasize that the magnitude of U_e3 is one of important ingredients to predict BR(μ → e + γ). Furtheremore, we examine the Shafi-Tavartkiladze model, which gives the inverse-hierarchical neutrino masses. Predicted branching ratios of μ → e + γ is smaller than the experimantal bound.
