N2 - The dynamics of baryogenesis or baryon asymmetry, which was produced at the electroweak phase transition (EWPT) by the Kobayashi-Maskawa (KM) phase, was investigated. The standard model (SM), which fulfilled the Sakharov conditions required for baryogenesis, was also discussed. It was found that KM mechanism was unable to account for the baryogenesis as the smallness of the quark flavor parameters suppresed CP violation strongly, while the mass of the Higgs boson is heavy for firstorder EWPT to occur. It was concluded that the baryogenesis is explained by the KM mechanism, provided there were no strong dilution factors coming from the dynamics.
