Abstract

We derive the lepton number violating dimension-five and dimension-seven operators, relevant for neutrino mass generation, in the Minimal Supersymmetry Standard Model without R-parity (the /RMSSM) by using the effective Lagrangian method. We keep all the possible CP violating phases, and we establish the general relationship between the high-scale parameters and the low-energy observals associated with the Standard Model particles. We study in a specific model the dependence of neutrino masses on the CP phases.
