This permits to search for a signature of particle showers induced by earth-skimming cosmic tau neutrinos in the PeV to EeV energy range arising from the ocean. We have studied the response of MAGIC to such events, employing Monte Carlo simulations of upward-going tau neutrino showers. The analysis of the shower images shows that air showers induced by tau neutrinos can be discriminated from the hadronic background coming from a similar direction. We have calculated the point source acceptance and the expected event rates, assuming an incoming tau neutrino flux consistent with IceCube measurements, and for a sample of generic neutrino fluxes from photo-hadronic interactions in AGNs. The analysis of about 30 hours of data taken toward the sea leads to a point source sensitivity for tau neutrinos at the level of the down-going point source analysis of the Pierre Auger Observatory. | Titolo del convegno: | 35th International Cosmic Ray Conference (ICRC2017) | Luogo del convegno: | Bexco, Busan, Korea | Periodo del convegno: | 10-20 July, 2017 | URI: | http://hdl.handle.net/20.500.12386/30133 | URL: | https://pos.sissa.it/301/ https://pos.sissa.it/301/992 |
