Abstract
We investigate leptogenesis in the E6 inspired Exceptional Supersymmetric Standard Model (E6SSM). Right-handed (RH) neutrinos are singlets under the Standard Model gauge groups and the extra U 1 gauge group of the E6SSM at low energies and are therefore not involved in gauge interactions. This allows them to have Majorana mass large enough for the seesaw mechanism and leptogenesis. In addition to canonical leptogenesis, the RH neutrinos may decay into exotic leptons and leptoquarks, the subsequent decays of which lead to extra lepton asymmetries. We find that the lepton asymmetry can be drastically enhanced as compared with that in the SM and MSSM?
