论文摘要
我们假设超出标准模型以外的任何颗粒足以在相变时集成，我们可以非扰动地研究一阶电子期。利用高温尺寸降低，我们执行晶格蒙特卡洛模拟来计算表征过渡的主要数量：临界温度，潜热，表面张力和气泡成核速率，更新并扩展了以前的晶格研究。我们关注该理论由于HIGGS自我耦合的有效降低而进行一阶相变的区域，并与扰动理论进行了详细的比较。
We study first-order electroweak phase transitions nonperturbatively, assuming any particles beyond the Standard Model are sufficiently heavy to be integrated out at the phase transition. Utilising high temperature dimensional reduction, we perform lattice Monte-Carlo simulations to calculate the main quantities characterising the transition: the critical temperature, the latent heat, the surface tension and the bubble nucleation rate, updating and extending previous lattice studies. We focus on the region where the theory gives first-order phase transitions due to an effective reduction in the Higgs self-coupling and give a detailed comparison with perturbation theory.
