    Sneutrino Dark Matter: Symmetry Protection and Cosmic Ray Anomalies
    (American Physical Society, 2010) Demir, Durmuş Ali; Demir, Durmuş Ali; Frank, Mariana; Selbuz, Levent; Turan, İsmail; 04.05. Department of Pyhsics; 04. Faculty of Science; 01. Izmir Institute of Technology
    We present an R-parity conserving model of sneutrino dark matter within a Higgsphilic U(1)′ extension of the minimal supersymmetric standard model. In this theory, the μ parameter and light Dirac neutrino masses are generated naturally upon the breaking of the U(1)′ gauge symmetry. One of the right-handed sneutrinos is the lightest supersymmetric particle. The leptonic and hadronic decays of another sneutrino, taken to be the next-to-lightest superpartner, allow for a natural fit to the recent results reported by the PAMELA experiment. We perform a detailed calculation of the dark matter relic density in this scenario, and show that the model is consistent with the ATIC and Fermi LAT experiments. © 2010 The American Physical Society.
