Leptogenesis in the E6SSM: Flavour Dependent Lepton Asymmetries
Abstract
We discuss flavour dependent lepton asymmetries in the Exceptional Supersymmetric Standard Model (E6SSM). In the E6SSM, the right-handed neutrinos do not participate in gauge interactions, and they decay into leptons and leptoquarks. Their Majorana nature allows violation of lepton number. New particles and interactions can result in substantial lepton asymmetries, even for scales as low as 106 GeV.
