Higher order corrections to muon cross sections — •Alexander Sandrock for the IceCube collaboration — Technische Universität Dortmund

The energy reconstruction of high-energetic muons in the IceCube neutrino observatory is based on the energy losses through electromagnetic interactions. The systematic uncertainties of IceCube are among others the result of uncertainties in the muon cross-sections for bremsstrahlung, pair production and photonuclear interaction. This presentation will give a brief overview about the status of currently used parametrizations and a new calculation for the bremsstrahlung cross section that also takes into account higher order corrections.
