论文摘要
在本文中，我们详细分析了具有特定真空配置的$ s_3 $ -symmetric三-HIGGS-DOUBLET模型。这种分析使我们能够说明具有多个HIGGS双重运动的模型的重要特征，例如有可能违反CP的可能性。我们从真正的潜力开始，然后选择一个特别有趣的复杂真空配置，在向潜力添加软性破坏术语之前，它不会违反CP。我们通过不同的软对称性破坏术语来研究r \^ ole。这些对于我们选择真空的必要条件是为了消除不必要的无质量标量，这是由于意外连续对称性的自发断裂而产生的。我们列出了我们在本工作中详细考虑的特定情况下列出标量扇区和标量范围的行业耦合。本文提出的结果将对模型构建有用，特别是对于具有$ S_3 $对称性和自发性CP违规的模型的实施，Fermionic部门的扩展具有逼真的Yukawa耦合以及暗物质研究。
In this paper we analyse in detail an $S_3$-symmetric three-Higgs-doublet model with a specific vacuum configuration. This analysis allows us to illustrate important features of models with several Higgs doublets, such as the possibility of having spontaneous CP violation. We start with a real potential and pick a particularly interesting complex vacuum configuration, which does not violate CP before adding soft breaking terms to the potential. We study the r\^ ole played by different soft symmetry breaking terms. These are essential for our choice of vacuum in order to remove unwanted massless scalars which arise from the spontaneous breaking of an accidental continuous symmetry. We list scalar sector and scalar-gauge sector-couplings for the particular case we consider in detail in this work. Results presented in this paper will be useful for model building, in particular for implementations of models with $S_3$ symmetry and spontaneous CP violation, extensions of the fermionic sector with realistic Yukawa couplings and for Dark Matter studies.
