dc.description.abstractWe explore the possibility of detecting horizontal electromagnetic showers of tau neutrinos from individual gamma ray bursts (GRBs), in large scale detectors such as HiRes and the Telescope Array. We study the role of the parameters of a gamma ray burst in determining the expected number of tau events from that burst. The horizontal beam of tau leptons produces visible signals in the atmosphere. We find that there is a slim chance of observing tau lepton appearances from GRBs with the Telescope Array. The number of signals is strongly dependent on the Lorentz factor Γ and the redshift z of a GRB, on the energy emitted in muon neutrinos and antineutrinos Eν,HE, and also on some other parameters of a GRB. It is possible to understand neutrino oscillations in astrophysical neutrinos and the mechanism or model of neutrino production inside a GRB by the detection or nondetection of tau lepton signals from it.en
