Inclined Cosmic Ray Air Showers in IceCube
Abstract
In this contribution we will consider the sensitivity of IceCube to inclined air showers produced by cosmic rays. Cosmic ray air shower analyses done with IceCube up to now only considered air showers arriving within a limited zenith angle range. IceTop analyses have included events up to about 40 degrees while coincident IceCube/IceTop analyses are limited to zenith angles smaller than 30 degrees. We study the possibility of extending the angular range to 60 degrees for both IceTop and coincident IceCube/IceTop. In the case of coincident IceCube/IceTop inclined events, the detector aperture is larger than that of IceTop at energies larger than 100 PeV due to the sensitivity to single muons at large distances from the shower axis. As part of this study, we have measured the average lateral distribution of muons at large distances to the shower axis.
