Leptogenesis in the E6SSM: Flavour Dependent Lepton Asymmetries
نویسندگان
چکیده
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.

Leptogenesis in the Exceptional Supersymmetric Standard Model: flavour dependent lepton asymmetries
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 ...
متن کاملFlavour Matters in Leptogenesis
We give analytic approximations to the baryon asymmetry produced by thermal leptogenesis with hierarchical right-handed neutrinos. Our calculation includes flavour-dependent washout processes and CP violation in scattering, and neglects gauge interactions and finite temperature corrections. Our approximate formulae depend upon the three CP asymmetries in the individual lepton flavours as well a...
متن کاملA fuller flavour treatment of N2-dominated leptogenesis
We discuss N2-dominated leptogenesis in the presence of flavour dependent effects that have hitherto been neglected, in particular the off-diagonal entries of the flavour coupling matrix that connects the total flavour asymmetries, distributed in different particle species, to the lepton and Higgs doublet asymmetries. We derive analytical formulae for the final asymmetry including the flavour c...
متن کاملOn the Impact of Flavour Oscillations in Leptogenesis
When lepton flavour effects in thermal leptogenesis are active, they introduce important differences with respect to the case in which they are neglected, the so-called one-flavour approximation. We investigate analytically and numerically the transition from the one-flavour to the two-flavour case when the τ -lepton flavour becomes distinguishable from the other two flavours. We study the impa...
متن کاملFlavor dependence of CP asymmetries and thermal leptogenesis with strong right-handed neutrino mass hierarchy
1550-7998=20 We prove that taking correctly into account the lepton flavour dependence of the CP asymmetries and washout processes, it is possible to obtain successful thermal leptogenesis from the decays of the second right-handed neutrino. The asymmetries in the muon and tau-flavour channels are then not erased by the inverse decays of the lightest right-handed neutrino N1. In this way, we re...
