Charged Lepton Flavor Violation in a class of Radiative Neutrino Mass Generation Models

We investigate the charged lepton flavor violating processes µ → eγ, µ → eee and µ − e conversion in nuclei for a class of three-loop radiative neutrino mass generation models with large electroweak multiplets. We show that the flavor violating processes µ → eγ and µ − e conversion in nuclei become highly suppressed compared to µ → eee process because of certain cancellations among various one-loop diagrams contributing to the effective µeγ and µeZ vertices in these models. Therefore, the observation of such pattern in LFV processes may reveal the radiative mechanism behind neutrino mass generation.
