Muon g −2, Dark Matter, and Lepton Flavor Violation in SUSY-GUT’s

Abstract

We perform an analysis of the predictions of several supersymmetric Grand Unified Theories (GUTs) for Dark Matter and the measurements of the muon anomalous magnetic moment (muon g − 2) consistent with possible Lepton Flavor Violating (LFV) signal in charged lepton decays. Each GUT predicts different Dark Matter (DM) scenarios, which can be used to classify SUSY models and contrast their predictions with experimental evidences. We find that models arising from SU(4)c × SU(2)L × SU(2)R can predict DM of cosmological interest while explaining the observed value of the muon g − 2. Furthermore, we show that when this framework is extended with a simple type 1 seesaw mechanism to explain neutrino masses, many models also predict charged LFV decays that can be observed in current experiments.
