I will talk about some new way to get a strongly first order phase transition in electroweak baryogenesis. Tranditionaly the phase transition is estimated by the high temperature expansion of the finite temperature potential, in which at leading order no contribution from fermions is seen. The new way is directly seen as a jump on the finite temperature JB JF curves. Contributions from the fermions are also get, which is comparable to the contribution of bosons, and with supersymmetric protection of the Higgs quartic coupling running the model can be tuned. We talk about two models, one is designed for Higgs diphoton decay enhancement, the other is a vector like new generation model.
