Minimal seesaw models and minimal lepton flavor violation.

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 μ → eγ and μ → 3e
