Baryogenesis from Mixing of Lepton Doublets
Bjorn Garbrecht
It is shown that the mixing of lepton doublets of the Standard Model can yield sizeable contributions to the lepton asymmetry, that is generated through the decays of right-handed…
Leptogenesis from a GeV Seesaw without Mass Degeneracy
Marco Drewes, Bjorn Garbrecht
For Leptogenesis based on the type-I seesaw mechanism, we present a systematic calculation of lepton-number violating and purely flavoured asymmetries within nonequilibrium Quantum…
Slow Roll during the Waterfall Regime: The Small Coupling Window for SUSY Hybrid Inflation
Sébastien Clesse, Björn Garbrecht
It has recently been pointed out that a substantial amount of e-folds can occur during the waterfall regime of hybrid inflation. Moreover, Kodama et.al. have derived analytic appro…
Leptogenesis from Additional Higgs Doublets
Bjorn Garbrecht
Leptogenesis may be induced by the mixing of extra Higgs doublets with experimentally accessible masses. This mechanism relies on diagrammatic cuts that are kinematically forbidden…
