Enhanced lepton flavor violation in the supersymmetric inverse seesaw model

We discuss a supersymmetric inverse seesaw model in which lepton flavor violating decays can be enhanced either by flavor violating slepton contributions or by the nonunitarity of the charged current mixing matrix. As an example we calculate Br(μ→eγ) taking into account both heavy lepton exchange as well as supersymmetric diagrams in a minimal supergravity framework. We find that for the same neutrino parameters the rate can be enhanced with respect to seesaw model expectations, with or without supersymmetry.
