Identification of starting muons in IceCube — •Sebastian Euler, Jan-Patrick Hülß, and Christopher Wiebusch — RWTH Aachen

The identification of starting muon tracks in IceCube is a way to separate neutrino induced events from the background of down-going atmospheric muons. We have developed an algorithm which calculates the likelihood of a track to start inside the detector volume and the likelihood to start outside. The algorithm is based on the detection probability of the generated Cherenkov photons. For each event the ratio of these likelihoods can be used as degree of believe of being neutrino induced. This algorithm is applied to the IceCube/DeepCore detector, which is a planned low energy enhancement of IceCube. The performance of the algorithm for neutrino induced down-going events is presented.
