Abstract

We investigate the charged lepton flavor violating processes μ→eγ, μ→eeē, and μ-e conversion in nuclei for a class of three-loop radiative neutrino mass generation models with electroweak multiplets of increasing order. We find that, because of certain cancellations among various one-loop diagrams which give the dipole and nondipole contributions in an effective μeγ vertex and a Z-penguin contribution in an effective μeZ vertex, the flavor violating processes μ→eγ and μ-e conversion in nuclei become highly suppressed compared to μ→eeē process. Therefore, the observation of such a pattern in LFV processes may reveal the radiative mechanism behind neutrino mass generation.
