Sneutrino Dark Matter: Symmetry Protection and Cosmic Ray Anomalies

Abstract

We present an R-parity conserving model of sneutrino dark matter within a Higgs-philic U(1)' extension of the minimal supersymmetric standard model. In this theory, the mu parameter and light Dirac neutrino masses are generated naturally upon the breaking of the U(1)' gauge symmetry. The leptonic and hadronic decays of sneutrinos in this model, taken to be the lightest and next-to-lightest superpartners, allow for a natural fit to the recent results reported by the PAMELA experiment.

Revised to match the published version; 11 pages (2 column format), 1 table, 6 figures, to appear in PRD
