Neutrino masses and a generic model of R-parity violation — Gautam Bhattacharyya1, Heinrich Päs2, and •Daniel Pidt2 — 1Saha Institute of Nuclear Physics, Kolkata - 700 064, India — 2Institut für Physik, TU Dortmund, 44221 Dortmund, Germany
Supersymmetry without R-parity provides a natural way to generate experimentally viable neutrino masses. In the most general case this adds 48 new complex parameters to the superpotential of the MSSM. We present an economic way based on two generic flavor symmetries to reduce the number of independent new couplings to six and investigate the resulting phenomenological consequences arising from the requirement to correctly reproduce neutrino oscillations.
