多Higgs偶态模型中的非解耦

Nondecoupling in Multi-Higgs doublet models

Francisco Faro, Jorge C. Romao, Joao P. Silva

摘要:

我们考虑模型与任何数量的希格斯偶极子和研究去耦的条件。我们表明,在非常一般的情况下,所有的二次系数的标量势必须存在,除了在特殊情况下,其中包括有关的条款消失的真空期望值的方向。我们举几个例子。此外,我们表明,所有带电标量的解耦意味着所有额外的中性标量的解耦和消失的$\mathcal{CP}$违反标量赝标混合。

英文摘要:

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.
