Abstract

The finite temperature phase transition in the SU(2)-Higgs model at a Higgs boson mass MH35M_H \simeq 35 GeV is studied in numerical simulations on four dimensional lattices with time-like extensions up to Lt=5L_t=5. Tc/MHT_c/M_H 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.
