Abstract
We calculate flavour dependent lepton asymmetries within the E6 inspired Supersymmetric Standard Model (E6SSM), which has an extra U(1)N symmetry. In this model, the right-handed neutrino doesn't participate in gauge interactions, allowing it to be used for both the see-saw mechanism and leptogenesis. Extra Higgs, leptons and leptoquarks predicted by the E6SSM contribute to the ordinary lepton CP asymmetries induced by the decays of the lightest right-handed neutrino (and sneutrino) and give rise to a set of extra decay asymmetries. We find that the CP asymmetries can be relatively large, even when the lightest right-handed neutrino is as light as 106 GeV.
