The recent observations with neutrino telescopes have opened a new window to the cosmos, giving the chance to explore very high-energy phenomena that can be potentially linked to new physics. The recent study on the the 6-year up-going muon neutrinos by the IceCube Collaboration and the multi-messenger analyses support the hypothesis of a two-component scenario explaining the diffuse TeV-PeV neutrino flux. Depending on the steepness of the astrophysical power-law, an excess in the IceCube data is shown in the energy range 10-100 TeV (low-energy excess) or at PeV (high-energy excess). The origin of such excesses is characterized by performing a statistical analysis on the neutrino energy spectrum and on the angular distribution of neutrino events. Such excesses could be explained in terms of a decaying/annihilating Dark Matter signal with mass of about 100 TeV up to few PeV. |
