Neutrino masses and Lepton-Flavor violation in R-Parity violating Supersymmetry — Heinrich Päs and •Daniel Pidt — Institut für Physik, TU Dortmund, 44221 Dortmund, Germany

Supersymmetry with trilinear R-parity violation (RPV) provides an interesting framework for the generation of neutrino masses without the need to introduce heavy right handed neutrinos. Within this framework we discuss the constraints on the RPV coupling products arising from a correct generation of the neutrino mass matrix in flavor space and the implications imposed on the decay rates of the lepton flavour violating decays µ → 3e, µ → eγ and the µ → e conversion in nuclei. We further compare the results with the predictions in standard seesaw scenarios and investigate the two P-odd asymmetries wich can be defined in the polarised µ → 3e decay.
