Minimal seesaw models and minimal lepton flavor violation

Abstract

We study the implications of the global $U(1{)}_R$ symmetry present in minimal lepton flavor violating implementations of the seesaw mechanism for neutrino masses. Our discussion is done in the context of explicit minimal type-I seesaw scenarios, where depending on the R-charge assignment different models can be constructed. We study the charged lepton flavor violating phenomenology of a concrete realization paying special attention to $\mu \to e\gamma$ and $\mu \to 3e$.
