摘要：

We study the possibility of having leptogenesis in an S-3 extension of the Standard Model with three Higgs doublets and three right-handed neutrinos. In the leptonic sector we introduce also a Z(2) symmetry to reduce further the number of parameters. The characteristics of the model allow in a very natural way for resonant leptogenesis, which is highly dependent on the values of the Dirac and Majorana phases. The associated baryogenesis is also maximal when the neutrino masses are almost degenerate.
