摘要
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(-1.17)(+5.87) x 10(-11), and this result agrees with experimental values very well. (C) 2001 Elsevier Science B.V. All rights reserved.
