Abstract

We study possible effects of non-local gravity corrections on the recent discovery by the IceCube collaboration reporting high-energy neutrino flux detected at energies of order PeV. Considering the 4-dimensional operator yαχLαˉHχ\sim y_{\alpha \chi}\bar{{L_{{\alpha}}}}\, H\, \chi, it is possible to explain both the IceCube neutrino rate and the abundance of Dark Matter, provided that non-local corrections are present in the cosmological background. Furthermore, the mechanism could constitute a natural way to address the H0H_0 tension issue.
