Study of flavour dependencies in leptogenesis

High Energy Physics - Phenomenology 2008-11-26 v2

Abstract

We study the impact of flavours on the efficiency factors and give analytical and numerical results of the baryon asymmetry taking into account the different charged lepton Yukawa contributions and the complete (diagonal and off-diagonal) LL to BLB-L conversion AA matrix. With this treatment we update the lower bound on the lightest right-handed neutrino mass.
