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, Y B = 1 . 46 +5 . 87 − 1 . 17 × 10 − 11 , and this result agrees with experimental values very well.
