论文摘要
为了计算电动eak相变的热力学，我们讨论了一种最小的方法，该方法可以调解量规不变性和热重新调整。这样的最小设置包括对三维有效理论的两循环维度的缩小，这是对有效潜力的一环计算及其在有效理论中围绕领先最小值的扩展。这种方法是可以处理的，并且为重新召集提供了公式，这比文献中无处不在的标准技术中出现的方法可以说得不复杂。特别是，我们实施了与硬热尺度相关的重量法化组改进。尽管具有通用性质，但我们为标准模型的复杂单线扩展提供了这种方法，该方法对高能量对撞机的现象学和暗物质预测具有有趣的前景。提出的表达式可用于对相变热力学和重力波产生的未来研究。
For computing thermodynamics of the electroweak phase transition, we discuss a minimal approach that reconciles both gauge invariance and thermal resummation. Such a minimal setup consists of a two-loop dimensional reduction to three-dimensional effective theory, a one-loop computation of the effective potential and its expansion around the leading-order minima within the effective theory. This approach is tractable and provides formulae for resummation that are arguably no more complicated than those that appear in standard techniques ubiquitous in the literature. In particular, we implement renormalisation group improvement related to the hard thermal scale. Despite its generic nature, we present this approach for the complex singlet extension of the Standard Model which has interesting prospects for high energy collider phenomenology and dark matter predictions. The presented expressions can be used in future studies of phase transition thermodynamics and gravitational wave production.
