Electroweak baryogenesis in the minimal supersymmetric standard model

We review the baryogenesis scenario in the MSSM at the perturbative level and, in particular, the impact of two-loop corrections on the strength of the phase transition and the amount of generated baryon asymmetry. We confirm the baryogenesis window, where m/sub H/<or approximately=115 GeV, for m...

Sumario:We review the baryogenesis scenario in the MSSM at the perturbative level and, in particular, the impact of two-loop corrections on the strength of the phase transition and the amount of generated baryon asymmetry. We confirm the baryogenesis window, where m/sub H/<or approximately=115 GeV, for m/sub Q/<or approximately=a few TeV, and the right-handed stop mass is constrained in the region, 100 GeV<or approximately=m/sub t/<or approximately=m/sub t/. This scenario will be tested at LEP and Tevatron colliders. (35 refs).
