Neutrino masses and mixing angles in SUSYGUT theories with explicit Rparity breaking
Abstract
In minimal SUSY GUT models the Rparity breaking terms are severely constrained by SU(5) gauge invariance. We consider the particular case where the explicit Rparity breaking occurs only via dimension2 terms of the superpotential. This model possesses only three Rparity breaking parameters. We have studied the predictions of this model for the neutrino masses and mixing angles at the oneloop level within the framework of a radiatively broken unified supergravity model. We find that this model naturally yields masses and mixing angles that can explain the solar and atmospheric neutrino problems. In addition, there are regions in parameter space where the solution to the solar neutrino puzzle is compatible with either the LSND result or the existence of significant hot dark matter neutrinos.
