摘要
We present new 4-D Monte Carlo results characterizing the strength of the finite temperature phase transition for Higgs/W mass ratios 1.0 and 0.6, obtained on isotropic lattices mainly with N-s = 16, N-t = 2. We discuss the distribution of an gauge invariant block spin order parameter, estimating the Higgs condensate phi(c) at T-c. We use the Potvin/Rebbi method in order to find the interface tension alpha/T-c(3). We demonstrate how the multi-histogram method (giving free energy differences) can be used to avoid the limiting procedure delta kappa --> 0. From pure-phase histograms at kappa(c), extrapolated with the help of this method, we estimate the latent heat Delta epsilon/T-c(4). Actual time series at lower Higgs mass require blocking in order to determine the jump of the lattice observables.
