Supersymmetric Lepton Flavor Violation

We study a new supersymmetric mechanism for lepton flavor violation in a minimal extension of the MSSM with low‐mass heavy singlet neutrinos, which is fully independent of the flavour structure of the soft SUSY breaking sector. We find that $l→l′γ$ processes are forbidden in the SUSY limit, whilst the processes $l→l′l1l2$ and $μ→e$ conversion in nuclei can be enhanced well above the observable level, via large neutrino Yukawa‐coupling effects.
