Electroweak corrections in supersymmetric models with broken R-parity — •Stefan Liebler — Institut für Theoretische Physik und Astrophysik, Universität Würzburg, D-97074 Würzburg

Supersymmetric models with broken R-parity provide an interesting alternative ansatz to explain neutrino physics, which is intrinsically supersymmetric. In most of these models one has to calculate the neutrino mass matrix at the one loop level to be consistent with current neutrino data. It turns out that also the one loop electroweak corrections to the decays of the lightest supersymmetric particle are important. Those show interesting correlations with the neutrino mixing angles, which can be tested at the LHC.
