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

Abstract

We investigate charged lepton flavor violating processes $\mu \to e\gamma$, $\mu \to ee\overline{e}$ and $\mu -e$ 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 non-dipole contributions in effective $\mu e\gamma$ vertex and Z-penguin contribution in effective $\mu eZ$ vertex, the flavor violating processes $\mu \to e\gamma$ and $\mu -e$ conversion in nuclei become highly suppressed compared to $\mu \to ee\overline{e}$ process. Therefore, the observation of such pattern in LFV processes may reveal the radiative mechanism behind neutrino mass generation.
