Highly-boosted dark matter and cutoff for cosmic-ray neutrino through neutrino portal

Abstract

We study the cutoff for the cosmic-ray neutrino, set by the scattering with cosmic background neutrinos into dark sector particles through a neutrino portal interaction. We find that a large interaction rate is still viable, when the dark sector particles are mainly coupled to the $\tau -$neutrino, so that the neutrino mean free path can be reduced to be $O(10)$Mpc over a wide energy range. If stable enough, the dark sector particle, into which most of the cosmic-ray neutrino energy is transferred, can travel across the Universe and reach the earth. The dark sector particle can carry the energy as large as $Ø(\mathrm{EeV})$ if originates from a cosmogenic neutrino.
