Abstract

We analyze a simple R-parity violating extension of the minimal supersymmetric standard model, with bilinear R-parity violation in the soft terms and VEVs, but not between the terms in the superpotential. The model gives two massive neutrinos, and can fit all constraints from neutrino data. We show analytically how to compute the lepton number violating Lagrangian parameters from neutrino masses and mixing angles. Conversely, we numerically vary the bilinear couplings as input parameters to determine the allowed ranges that are consistent with neutrino data. We briefly comment on the implications of our bounds for low energy lepton lepton-flavor violating processes.
