On the scaling of the electroweak interface tension at finite temperature

We determine the interface tension of the finite-temperature electroweak phase transition in a numerical investigation of the SU(2)–Higgs model on a four-dimensional lattice with temporal extension $L_t=3$. In this simulation the chosen parameters correspond to a Higgs boson mass of about 16 GeV. As a result the interface tension shows only small scaling violations in comparison with previous studies for $L_t=2$ lattices. We also report on some experiences with autocorrelations in the applied Monte Carlo simulations of two-phase systems.
