Abstract
We calculate the baryon asymmetry of the Universe in the standard mode l of the electroweak theory with CP violation appropriate for simple e xtensions of the Higgs sector. The propagation of quarks of masses up to about 5 GeV are considered, taking into account the effect of dampi ng rate. We find that the contribution of the b quark can still accoun t for the observed baryon asymmetry to within the theoretical uncertai nties of such models.
