Hunting for cosmogenic neutrinos with the ARIANNA experiment

The discovery of cosmogenic neutrinos is going to be a major milestone in high-energy neutrino astronomy. Due to the low flux of cosmogenic neutrinos effective volumes of at least an order of magnitude improvement of the size of the IceCube detector are needed. As optical methods are cost-prohibitive at these scales, the radio technique is most promising. The ARIANNA detector aims to detect neutrinos with energies above 1016 eV by instrumenting 0.5 Teratons of ice with a surface array of a thousand independent radio detector stations in Antarctica. Several pilot stations are currently operating successfully at the Moore's Bay site (Ross Ice Shelf) and at the South Pole. We will demonstrate the capabilities of the detector by reconstructing the signal direction and polarization from in-ice pulser studies and via the detection of the more abundant cosmic-ray air showers. Furthermore, we will discuss the science capabilities of ARIANNA.
