Abstract

We study ultrahigh energy astrophysical neutrinos and their interactions within the Standard Model and beyond. We consider propagation of muon neutrinos, tau neutrinos that originate in νµ → ντ oscillations, and tau leptons produced in charged-current neutrino interactions. We show that high energy taus lose their energy through bremsstrahlung, pair production and photonuclear processes until they reach energy of ∼ 10⁸ GeV, bellow which they are more likely to decay. Neutrino interactions at energies above 10⁸GeV could lead to the production of microscopic black holes predicted in theories of extra dimensions, or they can undergo instanton-induced processes. We discuss potential signals for these processes in detectors such as IceCube and ANITA.
