Abstract

We investigate CP violation in the decay process

by considering the interference effects of

, and

within the framework of the perturbative QCD method (P refers to π, K, η, and

pseudoscalar mesons). We analyze the mixings of

, and

and provide the amplitudes of the quasi-two-body decay processes. The CP violation for the

decay process is obvious in the ranges of the three vector meson interferences. Meanwhile, the localized CP violation can be found to compare with the experimental results from the three-body decay process at the LHC in the near future.

微扰 QCD 中三体衰变过程的共振贡献* * 河南省自然科学基金资助项目（232300420115）。

我们在微扰 QCD 方法框架内（P 指 π、K、η 和伪谱介子），通过考虑、、和的干涉效应，研究了衰变过程中的 CP 违约现象。我们分析了Ⅳ和Ⅴ的混合情况，并提供了准二体衰变过程的振幅。在三个矢量介子干涉的范围内，衰变过程的CP违反是显而易见的。同时，我们还发现了局部的CP违反，以便在不久的将来与大型强子对撞机三体衰变过程的实验结果进行比较。
