Detecting Very High Energy Neutrinos by the Telescope Array
  We present the cosmic neutrino detecting potential of the Telescope Array for quasihorizontally downward and upward air showers initiated by very high energy neutrinos penetrating the air and the Earth respectively. We adopted model predictions for extraterrestrial neutrino fluxes from active galactic nuclei, gamma-ray bursters, Greisen photo production, the collapse of topological defects, and Z-bursts. The Telescope Array, using a large array of bright and wide field-of-view flourescence telescopes, can esplore these very high energy cosmic neutrino sources.
