Findings

Models successfully generate neutrino masses radiatively.

Phenomenological implications include potential signals at TeV scale.

Novel mechanisms for lepton number violation in SUSY contexts.

Abstract

Radiative neutrino mass generation within supersymmetric (SUSY) construction is studied. The mechanism is considered where the lepton number violation is originating from the soft SUSY breaking terms. This requires MSSM extensions with states around the TeV scale. We present several explicit realizations based on extensions either by MSSM singlet or SU(2)_w triplet states. Besides some novelties of the proposed scenarios, various phenomenological implications are also discussed.
