Dark Matter Decay and Cosmic Rays

Abstract

The decay of dark matter is predicted by many theoretical models and can produce observable contributions to the cosmic-ray fluxes. I shortly discuss the interpretation of the positron and electron excess as observed by PAMELA and Fermi LAT in terms of decaying dark matter, and I point out the implications for the Fermi LAT observations of the gamma-ray flux with emphasis on its dipole-like anisotropy.
