  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.
