# Four-dimensional Simulation of the Hot Electroweak Phase Transition with the SU(2) Gauge-Higgs Model

## TL;DR

This paper investigates the nature of the finite-temperature phase transition in the four-dimensional SU(2) gauge-Higgs model for Higgs masses between 50 and 100 GeV, using lattice simulations to analyze transition order, interface tension, and latent heat.

## Contribution

It provides a systematic lattice study of the phase transition's order and thermodynamic properties for intermediate Higgs masses, extending understanding of the electroweak phase transition.

## Key findings

- Transition order varies with Higgs mass.
- Interface tension increases with Higgs mass.
- Latent heat behavior analyzed across mass range.

## Abstract

We study the finite-temperature phase transition of the four-dimensional SU(2) gauge-Higgs model for intermediate values of the Higgs boson mass in the range $50 \lsim m_H \lsim 100$GeV on a lattice with the temporal lattice size $N_t=2$. The order of the transition is systematically examined using finite size scaling methods. Behavior of the interface tension and the latent heat for an increasing Higgs boson mass is also investigated.
