论文摘要
未来的太空传播引力波（GW）探测器将为新物理学提供有前途的探测，即超出接收一阶相变的标准模型。 GW背景的预测在不同的混凝土粒子物理模型之间敏感，但在模型建筑物中也具有很大的堕落性，这激发了基于Electroweak对称性破坏（EWSB）的不同模式的相变的有效模型描述。 In this paper, using the scalar $N$-plet model as a demonstration, we propose an effective classification for three different patterns of EWSB: (1) radiative symmetry breaking with classical scale invariance, (2) Higgs mechanism in generic scalar extension, and (3) higher dimensional operators.我们得出的结论是，对于（1）和（2），可以实现强大的一阶过渡，并具有一个小的四分之一的耦合，以及带有经典尺度不变的轻标度场模型的额外的$ n $ n $ plet场，以及（3），并且在标量和$ n $ n $ n $ n $ n $ n $ -plet的范围之间进行大量混合。
The future space-borne gravitational wave (GW) detectors would provide a promising probe for the new physics beyond the standard model that admits the first-order phase transitions. The predictions for the GW background vary sensitively among different concrete particle physics models but also share a large degeneracy in the model buildings, which motivates an effective model description on the phase transition based on different patterns of the electroweak symmetry breaking (EWSB). In this paper, using the scalar $N$-plet model as a demonstration, we propose an effective classification for three different patterns of EWSB: (1) radiative symmetry breaking with classical scale invariance, (2) Higgs mechanism in generic scalar extension, and (3) higher dimensional operators. We conclude that a strong first-order phase transition could be realized for (1) and (2) with a small quartic coupling and a small isospin of an additional $N$-plet field for the light scalar field model with and without the classical scale invariance, and (3) with a large mixing coupling between scalar fields and a large isospin of the $N$-plet field for the heavy scalar field model.
