论文摘要
我们考虑具有任意数量的Higgs双重套件的模型，并研究解耦的条件。我们表明，在非常普遍的情况下，必须存在标量电位的所有二次系数，除非在特殊情况下，其中包括与消失真空期望值的方向相关的术语。我们举一些例子。此外，我们表明所有带电标量的解耦意味着在标量伪callioscalar混合中违反所有额外的中性标量和消失的$ \ Mathcal {cp} $违规。
We consider models with any number of Higgs doublets and study the conditions for decoupling. We show that, under very general circumstances, all the quadratic coefficients of the scalar potential must be present, except in special cases, which include terms related to directions of vanishing vacuum expectation values. We give a few examples. Moreover, we show that the decoupling of all charged scalars implies the decoupling of all extra neutral scalars and vanishing $\mathcal{CP}$ violation in scalar-pseudoscalar mixing.
