Manifestations of R-Parity Violation in Ultrahigh-Energy Neutrino   Interactions
  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 tau-leptons. We analyze the possible observable consequences of R-parity violating transitions in large-volume neutrino telescopes.
