[zh]许多与中性介子混合相关的可观测量已经被测量，这些实验测量可用于测试各种新的物理模型。双希格斯双峰模型是标准模型最简单的扩展之一。在本文中，B s 0− Bs 0、B d 0− Bd 0、D 0− D 0 和 K 0− K 0 混合在具有 C 型和 III 型的最小风味破坏双峰模型中进行了探索。首先，我们对中性介子混合的振幅进行完整的单循环计算。然后从所有相关的最新实验数据中获得真实和复杂情况下带电标量与夸克的汤川耦合的允许参数空间。最后，分析了相关观测值的理论预测以及III型和C型模型的差异。（论文）
[en] Many observables related to the neutral meson mixings have been measured, and these experimental measurements could be used to test various new physics models. The two-Higgs-doublet model is one of the simplest extensions of the standard model. In this paper, B s 0− Bs 0, B d 0− Bd 0, D 0− D 0 and K 0− K 0 mixings are explored in the minimal flavor violating two-Higgs-doublet models with type-C and type-III. Firstly, we perform a complete one-loop computation to the amplitudes of neutral meson mixings. Then the allowed parameter spaces of Yukawa couplings of charged scalars to quarks in both real and complex cases are obtained from all relevant latest experimental data. Finally, the theoretical predictions of relevant observables and the differences between type-III and type-C models are analyzed.(paper)
