Effects of the muon cross section uncertainties in IceCube — •Jan Soedingrekso, Tobias Hoinka, and Mirco Hünnefeld — TU Dortmund, Dortmund, Germany

The IceCube Neutrino Observatory measures astrophysical neutrinos through charged secondary particles emitting Cherenkov light. As the reconstruction of these secondaries, thus also the neutrinos, depend on the cross sections used in the Monte-Carlo Simulation, a systematic study regarding the uncertainties of these cross sections is needed. For high energy muons the energy loss processes are ionization, pair production and bremsstrahlung all with uncertainties of a few percents and inelastic nuclear interaction with an uncertainty of 10 to 20 percent. In this talk, the effects of different muon cross sections on the energy reconstruction are presented.
