Description

Recent observations by IceCube, notably two PeV cascades accompanied by events at energies $\sim (30-400)$ TeV, are clearly in excess over atmospheric background fluxes and beg for an astroparticle physics explanation. In this talk I will discuss the possibility to interpret the IceCube data by PeV mass scale decaying Dark Matter. I discuss generic signatures of this scenario, including its unique energy spectrum distortion with respect to the benchmark $E_\nu^{-2}$ expectation for astrophysical sources, as well as peculiar anisotropies. A direct comparison with the data show a good match with the above-mentioned features. I further discuss possible future checks of this scenario.
