Nonperturbative Condensates in the Electroweak Phase-Transition
摘要
We discuss the electroweak phase-transition in the early universe, using non-perturbative flow equations for a computation of the free energy. For a scalar mass above GeV, high-temperature perturbation theory cannot describe this transition reliably. This is due to the dominance of three-dimensional physics at high temperatures which implies that the effective gauge coupling grows strong in the symmetric phase. We give an order of magnitude-estimate of nonperturbative effects in reasonable agreement with recent results from electroweak lattice simulations. (Talk given by C.
