More about Electroweak Baryogenesis in the Minimal Supersymmetric Standard Model
Antonio Riotto
Abstract
We compute the baryon asymmetry generated at the electroweak phase transition by the Higgs scalar sector of the minimal supersymmetric standard model. Because of large enhancement effects from low momentum modes, Higgs particles may be responsible for the observed baryon asymmetry even though CP-violation in the Higgs sector only appears at the one-loop level. We also discuss the approximations made in the analysis and suggest possible improvements.
