Electroweak phase transition by four dimensional simulations
Abstract
The finite temperature phase transition in the SU(2)-Higgs model at a Higgs boson mass MH 35 GeV is studied in numerical simulations on four dimensional lattices with time-like extensions up to Lt=5. Tc/MH is extrapolated to the continuum limit and a comparison with the perturbative prediction is made. A one-loop calculation to the coupling anisotropies of the SU(2)-Higgs model on lattices with asymmetric lattice spacings is presented. Our numerical simulations show that the above perturbative result is applicable in the phenomenologically interesting parameter region.
