当CP中的C不重要时:四阶CP本征态及其Yukawa相互作用的剖析

When the C in CP does not matter: anatomy of order-4 CP eigenstates and their Yukawa interactions

Alfredo Aranda, Igor P. Ivanov, Enrique Jiménez

摘要:

我们探讨的起源和汤川相互作用的标量与奇特的CP-最近发现的一个多希格斯模型的基础上的4阶CP对称性的属性。我们将这些标量的存在与定义CP的增强自由度相关联,甚至超越了众所周知的广义CP对称性,这种对称性出现在具有几个零电荷标量场的模型中。我们还表明,尽管具有异国情调的CP量子数,这些标量不必是惰性的:他们可以有CP守恒汤川相互作用提供的CP费米子的行为也混合世代。本文着重于形式方面-暴露在教学的方式-包括可能的现象学后果的简要讨论。

英文摘要:

We explore the origin and Yukawa interactions of the scalars with peculiar CP-properties which were recently found in a multi-Higgs model based on an order-4 CP symmetry. We relate the existence of such scalars to the enhanced freedom of defining CP, even beyond the well-known generalized CP symmetries, which arises in models with several zero-charge scalar fields. We also show that despite possessing exotic CP quantum numbers, these scalars do not have to be inert: they can have CP-conserving Yukawa interactions provided the CP acts on fermions by also mixing generations. This paper focuses on formal aspects---exposed in a pedagogical manner---and includes a brief discussion of possible phenomenological consequences.
