High energy neutrino interactions

Research output: Contribution to conferencePaperpeer-review

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.
