Contribution

It introduces a 3D lattice formalism for accurate simulation of the electroweak phase transition, enabling precise measurements and a clear relation to perturbative approaches.

Findings

Measured critical temperature, latent heat, and interface tension for Higgs masses up to 70 GeV.

Achieved continuum and infinite volume extrapolations for reliable results.

Established a consistent link between non-perturbative lattice results and perturbation theory.

Abstract

We study the phase transition in SU(2)-Higgs model on the lattice using the 3D dimensionally reduced formalism. The 3D formalism enables us to obtain highly accurate Monte Carlo results, which we extrapolate both to the infinite volume and to the continuum limit. Our formalism also provides for a well-determined and unique way to relate the results to the perturbation theory. We measure the critical temperature, latent heat and interface tension for Higgs masses up to 70 GeV.
