Lepton flavor violating process in degenerate and inverse-hierarchical neutrino models

We have investigated the lepton flavor violation in the supersymmetric framework assuming the large mixing angle MSW solution with the quasidegenerate and the inverse-hierarchical neutrino masses. In the case of the quasidegenerate neutrinos, the predicted branching ratio BR(μ→eγ) strongly depends on mν and Ue3. For Ue3≃0.05 with mν≃0.3 eV, the prediction is close to the present experimental upper bound if the right-handed Majorana neutrino masses are degenerate. On the other hand, the prediction is larger than the experimental upper bound for Ue3⩾0.05 in the case of the inverse-hierarchical neutrino masses.
