Manifestations of R-parity violation in ultrahigh-energy neutrino interactions

Abstract

Supersymmetric couplings that do not respect R-parity can induce significant changes in the interaction rates of ultrahigh-energy neutrinos through the direct-channel production of superpartner resonances, and can provide new sources of extremely energetic τ-leptons. We analyze the possible observable consequences of R-parity violating transitions in large-volume neutrino telescopes.
