Higher order corrections to muon cross sections(pdf)

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 to a certain extent the result of uncertainties in the muon cross sections for bremsstrahlung, pair production and photonuclear interaction. This presentation will give a brief overview of the status of currently used parametrizations and a new calculation for the bremsstrahlung cross section that also takes into account higher order corrections.
