[NU092] Radio Detection of Ultra-High Energy Neutrino-Induced Tau Lepton Air Showers at High Altitudes

Although cosmogenic neutrinos are expected to be produced in predominantly electron and muon flavors, neutrino mixing predicts that, upon arrival to Earth, tau neutrinos will will be found in equal ratios. The Auger Observatory is sensitive to air showers produced by tau-leptons from tau-neutrino interactions in the Earth and has produced one of the most restrictive limits. Recently, other experiments have been proposed to extend the sensitivity to this channel. We present a study on the sensitivity of ultra-high energy tau lepton air showers using radio detectors at high altitudes. This includes the effects of ice or ocean layers of varying thickness along with uncertainties in the neutrino-nucleon interaction cross-section and tau lepton energy loss due to photonuclear interactions.
