Supersymmetric Lepton Flavor Violation

TL;DR

This paper introduces a supersymmetric mechanism for lepton flavor violation that operates independently of the soft SUSY breaking sector, highlighting potential observable processes like l -> l'l1 l2 and mu -> e conversion.

Contribution

It proposes a novel supersymmetric mechanism for lepton flavor violation that is independent of the soft SUSY breaking sector and predicts enhanced observable processes.

Findings

l -> l' gamma processes are forbidden in the SUSY limit

l -> l'l1 l2 and mu -> e conversion can be significantly enhanced

The mechanism operates independently of the flavor structure of the soft SUSY breaking sector

Abstract

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 flavor structure of the soft SUSY breaking sector. We find that l -> l' gamma processes are forbidden in the SUSY limit, whilst the processes l -> l'l1 l2 and mu -> e conversion in nuclei can be enhanced well above the observable level, via large neutrino Yukawa-coupling effects.
