Extended implementation of cross sections in the propagation tool of charged leptons PROPOSAL — •Mario Dunsch for the IceCube collaboration — TU Dortmund, Deutschland

The recorded data of large underground detectors like the neutrino telescope IceCube are at a stage where in many analyses the sensitivity is rather limited by systematic than the statistical uncertainties. The systematic ones occur from imprecise theoretical descriptions for the Monte Carlo simulations, wherefore it is necessary to improve such descriptions. One part of the Monte Carlo chain used for IceCube is the program PROPOSAL (Propagator with optimal precision and optimized speed for all leptons), which simulates the propagation of leptons through media. The aim of this thesis is to implement and to test improved cross sections in PROPOSAL, whereby the focus is placed on pair production and bremsstrahlung. Furthermore, improved cross sections for supersymmetric staus are implemented which can be used to probe physics beyond the standard model.
