A Heavy Higgs Can Give Strong First Order Electroweak Phase Transition in the Standard Model

The role of Higgs sector of the standard model in first order phase transition is reexamined.It is found that a solution to the mass gap equations exist which can be used in higher orders. This possible solution leads to a transition which is found to be strongly first order and the ratio of the critical scaler field and the critical temperature is about 1.2 for a Higgs of mass around 400 GeV.This can explain baryogenesis.
