We study the interactions of quarks and antiquarks with the changing Higgs
field during the electroweak phase transition, including quantum mechanical and
some thermal effects, with the only source of CP violation being the known CKM
phase. The magnitude and sign of the predicted BAU agrees with the observed
value, with moderately optimistic assumptions about the dynamics of the phase
transition. At present uncertainties related to the dynamics of the ew phase
transition and the oversimplifications of our treatment are too great to decide
whether or not this is the correct explanation for the presence of remnant
matter in our universe, however the present work makes it clear that the
minimal standard model cannot be discounted as a contender for explaining this
phenomenon.Comment: 121pp plus 14 figures, CERN-TH.6734/93 and RU-93-11. latex. This is
an extended version of the preprint originally issued in May, 1993. It
corrects some typographical errors and has been somewhat reorganized (e.g.,
moving more to the appendices) and elaborated (especially the section on
analytic results) in order to make it more readily understandable. In
addition we include two effects which were previously neglected: L−R mixing
due to QCD sphalerons, and a diminution of the electroweak gauge and Higgs
effects in the broken phase due to mass corrections in the 1-loop
approximation to th
