[NU064] Radio search for EHE neutrinos with the ARIANNA pilot array, and ARIANNA performance projections
The ARIANNA project seeks to observe cosmogenic neutrinos in the energy range of 10^16 to 10^21 eV through the use of a grid of over 1000 independent radio detector stations. These stations search for the characteristic Askaryan radio pulses, from particle cascades generated in the ice by these neutrinos, with a bandwidth of 50 - 1000 MHz. Spaced a kilometer apart, this array would effectively survey nearly 1000 cubic kilometers of Antarctic ice. Currently, the Hexagonal Radio Array (HRA) at the Moore's Bay site (Ross Ice Shelf) serves as a pilot for the ARIANNA concept. A neutrino signal analysis will be presented using data from two years of HRA operation, along with an updated neutrino flux limit. We will also discuss the projected sensitivity of the full ARIANNA array using real-world performance data from the HRA, and show that ARIANNA will be able to probe conservative models of the GZK neutrino flux.
