Abstract

We give the nonperturbative phase diagram of the four-dimensional hot electroweak phase transition. A systematic extrapolation a → 0 is done. Our results show that the finite temperature SU(2)-Higgs phase transition is of first order for Higgs-boson masses m_H < 66.5 ± 1.4 GeV. The full four-dimensional result agrees completely with that of the dimensional reduction approximation. This fact is of particular importance, because it indicates that the fermionic sector of the Standard Model (SM) can be included perturbatively. We obtain that the Higgs-boson endpoint mass in the SM is 72.4 ± 1.7 GeV. Taking into account the LEP Higgs-boson mass lower bound excludes any electroweak phase transition in the SM.
