IceVeto: An Extension of IceTop to Veto Air Showers for Neutrino Astronomy with IceCube — •Jan Auffenberg für die IceCube Kollaboration — III. Physikalisches Institut, RWTH Aachen, D-52056 Aachen

IceCube is the world's largest high-energy neutrino observatory, built at the South Pole. For neutrino astronomy, a large background-free sample of well-reconstructed neutrinos is essential. The main background for this signal are muons and neutrinos which are generated in cosmic-ray air showers in the Earth's atmosphere. The coincident detection of these air showers by the surface detector IceTop has been proven to be a powerful veto for atmospheric neutrinos and muons in the field of view of the southern hemisphere. This motivates this study to significantly extend IceTop in a cost-efficent way and to explore the increased physics potential. First simple estimates indicate that such a veto detector will more than double the discovery potential of current point source analyses. Here, we present the motivation and capabilities based on first simulations.
