Baryogenesis via lepton number violation in Anti-GUT model

We study the baryogenesis via lepton number violation in the model of Anti-GUT. The origin of the baryogenesis is the existence of right-handed Majorana neutrinos which decay in a C, CP and lepton number violation way. The baryon number asymmetry is calculated in the extended Anti-GUT model which is only able to predict order of magnitude-wise. We predicted baryon number to entropy ratio, YB=1.46+5.87−1.17×10−11, and this result agrees with experimental values very well.
