parity violation from discrete symmetries
arXiv:1410.3474 · doi:10.1016/j.nuclphysb.2014.12.011
Abstract
We consider supersymmetric extensions of the standard model in which the usual or matter parity gets replaced by another or non- discrete symmetry that explains the observed longevity of the nucleon and solves the problem of MSSM. In order to identify suitable symmetries, we develop a novel method of deriving the maximal symmetry that satisfies a given set of constraints. We identify parity violating (RPV) and conserving models that are consistent with precision gauge unification and also comment on their compatibility with a unified gauge symmetry such as the Pati-Salam group. Finally, we provide a counter-example to the statement found in the recent literature that the lepton number violating RPV scenarios must have term and the bilinear operator of comparable magnitude.
