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) to conversion matrix. With this treatment we update the lower bound on the lightest right-handed neutrino mass.
