Soft See-Saw: Radiative Origin of Neutrino Masses in SUSY Theories

Understand

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.
