Planck-scale effects on WIMP dark matter

Abstract

Weakly Interactive Massive Particles are among the most motivated candidates invoked to solve the Dark Matter puzzle. The stability of Dark Matter (DM) typically results from a global protective symmetry. However, the presence of gravitational effects may cause its explicit breaking. We show that this provides a new source of signal for indirect DM searches as well as the embedding of a large class of decaying Dark Matter models into the WIMP paradigm.
