Characterizing the search for UHE neutrinos with the ARIANNA detector

摘要

The ARIANNA experiment exploits unique properties of the Ross Ice Shelf, namely its radio transparencyand radio reflectivity at the ice-water boundary beneath the shelf, to search for UHE neutrinos. Simulation studies showthat, with the full array, we can expect to detect 40 GZK events/year using the ESS model. The excellent sensitivityresults from the low energy threshold (> 3 × 1017 eV), large volume (513 km 3 ), and viewing slightly more than halfthe sky. We have developed simulation tools to estimate the sensitivity to all neutrino flavors. In this paper, we will alsopresent the angular coverage and energy dependent sensitivity of the detector.
