论文摘要
尽管标准模型超过标准模型的额外标量多重组可以导致强大的电子相变，但取决于其量子数，但它也可能面临理论和实验的关键约束。如果有多个多重副本的副本以上，则可以预测该数字从强大的电动相位过渡的要求和与最新约束的一致的要求中。我们的目标是在本研究中探讨这一特定问题，以全球o $ $（n）$对称性管理的$ n $ n $变性标量三重态。我们将重要的限制从$ H \折叠到γγ$信号强度，暗物质直接检测和Landau极行为。一个组合的分析显示，$ n \ gtrsim 70 $，用于强阶段过渡和与约束的一致性。我们还研究了感兴趣的参数区域中可能的重力波信号。
While an additional scalar multiplet over and above the Standard Model can lead to a strong electroweak phase transition, depending on its quantum numbers, it also potentially confronts crucial constraints from theory and experiments. Should there exist more than one copy of such a multiplet, it is possible to predict that number from the requirements of a strong electroweak phase transition and agreement with the latest constraints. We aim to probe this specific issue in this study in the context of $N$ degenerate scalar triplets governed by a global O$(N)$ symmetry. We fold in important constraints from $h \to γγ$ signal strength, dark matter direct detection and Landau pole behaviour. A combined analysis reveals $N \gtrsim 70$ for a strong phase transition and consistency with the constraints. We also look into possible gravitational wave signals in the parameter regions of interest.
