Lepton Electric Dipole Moments, Supersymmetric Seesaw and Leptogenesis Phase

Abstract We calculate the lepton electric dipole moments in a class of supersymmetric seesaw models and explore the possibility that they may provide a way to probe some of the CP violating phases responsible for the origin of matter via leptogenesis. We show that in models where the right handed neutrino masses, MR arise from the breaking of local B-L by a Higgs field with B-L=2, some of the leptogenesis phases can lead to enhancement of the lepton dipole moments compared to the prediction of models where MR is either directly put in by hand or is a consequence of a higher dimensional operator.
