Comprehensive analysis of anomalous ANITA events disfavors a diffuse tau-neutrino flux origin
Original language description
Recently, the ANITA collaboration reported on two upward-going extensive air shower events consistent with a primary particle that emerges from the surface of the Antarctic ice sheet. These events may be of nu(tau) origin, in which the neutrino interacts within the Earth to produce a tau lepton that emerges from the Earth, decays in the atmosphere, and initiates an extensive air shower. In this paper we estimate an upper bound on the ANITA acceptance to a diffuse nu(tau) flux detected via tau-lepton-induced air showers within the bounds of standard model uncertainties. By comparing this estimate with the acceptance of Pierre Auger Observatory and IceCube and assuming standard model interactions, we conclude that a nu(tau) origin of these events would imply a neutrino flux at least two orders of magnitude above current bounds.
