论文摘要
复合希格斯模型假设希格斯场是作为伪金模式出现的，该模式对应于新的强耦合扇区中的动态对称性破裂。我们提出了一个软壁全息模型，其中这种对称性破坏是作为一阶相变的。在这种情况下，早期宇宙中的气泡成核成为可能。为了研究这种类型模型中的均质解决方案，我们提出了扰动理论方法。我们估计成核阶段产生的重力波谱，并发现可以通过计划的重力波检测器检测到它。
The composite Higgs model assumes that the Higgs field arises as the pseudo-Goldstone mode corresponding to a dynamical symmetry breaking in a new strongly coupled sector. We present a soft-wall holographic model where such symmetry breaking occurs as a first order phase transition. In this case the bubble nucleation in the early universe becomes possible. To study the homogeneous solutions in the models of this type we present the perturbation theory approach. We estimate the gravitational wave spectrum produced during the nucleation phase and find it to be detectable with the planned gravitational wave detectors.
