Lepton number violating mSUGRA and neutrino masses

Abstract

We perform a quantitative study of neutrino phenomenology in the framework of minimal supergravity (mSUGRA) with grand unified theory (GUT)-scale tri-linear lepton number violation. We show that only two non-zero GUT scale lepton number violating parameters and three charged lepton mixing angles are sufficient to account for current neutrino oscillation data. This allows collider studies to be performed in a manageable parameter space. We discuss some phenomenological consequences of the models, including tuning issues.
