| Summary:
Cosmic rays scattering with neutrinos produced in supernovae induce a flux of
supernova neutrinos boosted to high energies. We calculate the neutrino flux
arising from this new mechanism in environments with large cosmic-ray and
supernova densities, such as some Active Galactic Nuclei. Under plausible
astrophysical conditions, this flux may be detectable with high-energy neutrino
telescopes, just considering the proton-neutrino scattering cross section
expected in the Standard Model. Furthermore, the center of mass energy of such
scatterings can reach $ sqrts sim 10-100$ TeV, where the proton-neutrino
cross section may be enhanced by new physics such as extra-dimensional
theories. The boosted neutrino signal benefits from such an enhancement in the
cross section not only at the detection point on Earth, but also at production
in astrophysical sources, which allows us to set novel constraints on the
ultra-high energy proton-neutrino cross section with neutrino telescopes.
