摘要

本文利用三维标准模型有效场论，在双环水平下研究了电弱相变。我们观察到，用量规不变方法得到的相变参数与用朗道量规得到的相变参数相差约百分之一。我们给出了电弱重子发生的强一阶相变条件，并发现在新的物理尺度Λ > 590GeV下引力波信号将被减小，并且在Λ > 570 GeV的参数空间可以被LISA、天琴和太极等天基干涉仪探测到。2025年由美国物理学会出版

First-order electroweak phase transition with a gauge-invariant approach

We study the electroweak phase transition with a three-dimensional standard model effective field theory at the two-loop level under a gauge-invariant approach. We observe that the phase transition parameters obtained with the gauge-invariant approach deviate from that obtained in the Landau gauge at around the percent level. We give the strongly first-order phase transition condition for electroweak baryogenesis and find that the predicted gravitational wave signals would be reduced for the new physics scale Λ≲590GeV, and the parameter spaces of Λ≲570 GeV can be probed by the space-based interferometers, such as LISA, TianQin, and Taiji.
