PAMELA , DAMA , INTEGRAL and Signatures of Metastable Excited WIMPs

Abstract

Models of dark matter with ∼ GeV scale force mediators provide attractive explanations of many high energy anomalies, including PAMELA, ATIC, and the WMAP haze. At the same time, by exploiting the ∼ MeV scale excited states that are automatically present in such theories, these models naturally explain the DAMA/LIBRA and INTEGRAL signals through the… (More)
