暗禁闭与手征相变:引力波与物质表象

Dark Confinement and Chiral Phase Transitions: Gravitational Waves vs Matter Representations

Manuel Reichert, Francesco Sannino, Zhi-Wei Wang, Chen Zhang

摘要:

我们研究了引力波信号产生的强耦合模型,具有暗手征和限制相变。因此,我们确定强耦合的理论,可以具有一阶相变。采用Polyakov-Nambu-Jona-Lasinio模型,我们将注意力集中在SU(3)Yang-Mills理论上,这些理论以费米子的基本表示、伴随表示和双指数对称表示为特征。我们发现,对于引力波信号的分析,有显着差异的各种表示。有趣的是,我们还观察到,双指数对称表示导致最强的一阶相变,因此被大爆炸观察者实验检测到的机会更高。我们对禁闭和手征相变的研究进一步适用于以复合动力学为特征的标准模型的扩展。

英文摘要:

We study the gravitational-wave signal stemming from strongly coupled models featuring both, dark chiral and confinement phase transitions. We therefore identify strongly coupled theories that can feature a first-order phase transition. Employing the Polyakov-Nambu-Jona-Lasinio model, we focus our attention on SU(3) Yang-Mills theories featuring fermions in fundamental, adjoint, and two-index symmetric representations. We discover that for the gravitational-wave signals analysis, there are significant differences between the various representations. Interestingly we also observe that the two-index symmetric representation leads to the strongest first-order phase transition and therefore to a higher chance of being detected by the Big Bang Observer experiment. Our study of the confinement and chiral phase transitions is further applicable to extensions of the Standard Model featuring composite dynamics.
