摘要：

We reexamine the electroweak baryogenesis within the context of the minimal supersymmetric standard model, studying its potential collider signatures. We find that this mechanism of baryogenesis does not give a new CP violating signal at the B factories. The first circumstantial evidence may come from enhanced B-s or B-d mixing. If a light right-handed scalar top quark and Higgs boson are found as required, a linear collider represents the best possibility for confirming the scenario.
