Abstract

The proposed Saltdome Shower Array (SalSA) experiment will detect coherent Cherenkov radio signals from high-energy neutrino interactions in a naturally occurring salt dome. By identifying the number and the angular profile of radio emissions in any given event, distinction can be made between charged-current (CC) and neutral-current (NC) neutrino interactions. Additionally, the flavor of the neutrino can be identified in the case of charged-current interactions. Preliminary results for nominal GZK neutrino flux indicate that ~25% of all events can be correctly identified as coming from charged-current interactions of νμ's or ντ's. These charged-current initiated events can further be separated by the flavor of the original neutrino, either νμ's or ντ's.
