Description

SUSY models with broken R-partiy 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. As the same paramters govern neutrino physics and LSP decays one obtains interesting correlations between the LSP decay properties and and neutrino mixing angles. For this purpose full electroweak corrections to the LSP decays have to be taken into account. We discuss some technical details of the electroweak corrections to the LSP decay, which can also easily be used for the decays of the heavier neutralinos in the MSSM as well as the NMSSM.
