Existence and properties of the electroweak phase transition in the early universe depend strongly on the mass of the Higgs scalar MH. There is presumably no true symmetry restoration at high temperature. Nevertheless, a first order phase transition occurs in the standard model for M H ≲ GeV. For a realistic scalar mass M ≳ GeV the transition to the high temperature regime is described by a crossover, due to the strong electroweak gauge interactions for temperatures near and above the critical…

High Temperature Field Theory Beyond Perturbation Theory

For realistic values of the Higgs boson mass the high temperature electroweak phase transition cannot be described perturbatively. The symmetric phase is governed by a strongly interacting SU(2)

The Weak Electroweak Phase Transition

Abstract We present a detailed analysis of the phase transition in the standard model at finite temperature. Using an improved perturbation theory, where plasma masses are determined from a set of

Is There a Hot Electroweak Phase Transition at mH >~ mW?

Non-perturbative evidence is provided for the fact that there is no hot electroweak phase transition at large Higgs masses, and the line of first order phase transitions separating the symmetric and broken phases at small $m_H$ has an end point.
