Abstract
We compute the baryon asymmetry generated at the electroweak phase tra nsition by the Higgs scalar sector of the minimal supersymmetric stand ard model. Because of large enhancement effects from low momentum mode s, Higgs particles may be responsible for the observed baryon asymmetr y even though CP-violation in the Higgs sector only appears at the one -loop level. We also discuss the approximations made in the analysis a nd suggest possible improvements.
