Towards Reviving Electroweak Baryogenesis with a Fourth Generation

Table 1

The -dependent squared masses and the number of degrees of freedom for particle in SM. gives the physical masses for  GeV, which is the vacuum expectation value of the Higgs field. are given for scheme. We include the contributions coming from the Higgs boson , the would-be Nambu-Goldstone bosons , the gauge bosons and , and the top quark .
