论文摘要
我们计算了由Electroweak相变的引力波光谱，该光谱在早期宇宙中使用TEV尺度超出标准模型物理学产生。我们的研究捕获了非扰动框架内量子和热波动的影响。我们发现平均气泡分离与相变强度参数之间的普遍关系，该参数具有广泛的新物理贡献。 该结果的后果是三个方面：首先，它们限制了由重量（TEV尺度）新物理学产生的重力波光谱。其次，它们有助于将重物与重力波的较重区分与重力波签名。第三，他们认为，可能需要进行重力波观测的一致努力以及对撞机实验，以区分不同的重型新物理模型。
We calculate the gravitational-wave spectra produced by the electroweak phase transition with TeV-scale Beyond-Standard-Model physics in the early universe. Our study captures the effect of quantum and thermal fluctuations within a non-perturbative framework. We discover a universal relation between the mean bubble separation and the strength parameter of the phase transition, which holds for a wide range of new-physics contributions. The ramifications of this result are three-fold: First, they constrain the gravitational-wave spectra resulting from heavy (TeV-scale) new physics. Second, they contribute to distinguishing heavy from light new physics directly from the gravitational-wave signature. Third, they suggest that a concerted effort of gravitational-wave observations together with collider experiments could be required to distinguish between different models of heavy new physics.
