论文摘要
在过去的几年中，我们目睹了一些风味异常，基于扩展量规部门的解释是最受欢迎的解决方案之一。这些超出标准模型（SM）理论通常会假设由新向量玻色子介导的风味变化，但与此同时，它们可能会产生$ k^{0} - \ bar {k}^{0} $，$ d^{0} $ d^{0} - \ bar {d} - \ bar {d}^0}^0} $ b^0_ b^0_d-b^0_d-b^0_d} $ b^0_s- \ bar {b^0} _s $ Meson Systems。利用有关这些介子系统质量差异的最新数据，我们在Quark混合矩阵的两个不同参数化的矢量介体上得出了较低的质量界限。根据弱SU（3）量规组的基本表示，专注于一个充分动机的模型，我们将发现与当前和未来的强子山子相结论，得出结论，结论是，梅森大规模系统可以产生比起$ b \ rightorw s $ $ s $ $ s $ $ nef（d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^d^不利。
We have witnessed some flavor anomalies appeared in the past years, and explanations based on extended gauge sectors are among the most popular solutions. These beyond the Standard Model (SM) theories often assume flavor changing interactions mediated by new vector bosons, but at the same time they could yield deviations from the SM in the $K^{0}-\bar{K}^{0}$, $D^{0}-\bar{D}^{0}$, $B^0_d-\bar{B^0}_d$ and $B^0_s-\bar{B^0}_s$ meson systems. Using up-to-date data on the mass difference of these meson systems, we derive lower mass bounds on vector mediators for two different parametrizations of the quark mixing matrices. Focusing on a well-motivated model, based on the fundamental representation of the weak SU(3) gauge group, we put our findings into perspective with current and future hadron colliders to conclude that meson mass systems can give rise to bounds much more stringent than those from high-energy colliders and that recent new physics interpretations of the $b\rightarrow s$ and $R(D^{\ast})$ anomalies are disfavored.
