Title: Indirect Probes of the Dark Sector

Abstract:

In the last year PAMELA and Fermi satellites reported anomalies in Cosmic Rays fluxes. Different ideas have been invoked to explain it, some involving Dark Matter annihilating (or decaying) in our Galaxy. In this talk I will present the current status of the Dark Matter explanation. In particular I will explain why such interpretation suggests the presence of an "hidden" sector with new light particles very weakly coupled to the Standard Model. Possible ways to probe this new sector with current and future experiments will be discussed.
