复合2-Higgs双重态模型中的CP破坏

CP-Violation in a Composite 2-Higgs Doublet Model

Stefania De Curtis, Stefano Moretti, Ryo Nagai, Kei Yagyu

摘要:

研究了基于整体对称性破缺$SO(6)/[SO(4)\times SO(2)]$的复合2-Higgs双重态模型(C2 HDM)中的CP破坏(CPV),其中强扇区用两个场点的驼鹿结构来模拟.在涉及基本扇区和强扇区中费米子的相互作用中,非平凡的复杂相可以在希格斯势和汤川耦合参数中诱发CPV。我们计算后者,并分析其依赖于上述复杂的阶段。最后,我们讨论了这个模型的物理可观测量。即使在最简单的情况下,在强扇区中只有一个复杂的相位,我们也可以得到显着的CPV效应。

英文摘要:

We study CP-Violation (CPV) in a Composite 2-Higgs Doublet Model (C2HDM) based on the global symmetry breaking $SO(6)/[SO(4)\times SO(2)]$, wherein the strong sector is modeled by a two-site moose structure. Non-trivial complex phases in the interactions involving fermions in both the elementary and strong sectors can induce CPV in the Higgs potential as well as the Yukawa coupling parameters. We compute both of the latter and analyse their dependence upon the aforementioned complex phases. Finally, we discuss physics observables which are distinctive of this model. Even in the simplest case with only one complex phase in the strong sector we can get significant CPV effects.
