摘要：
在LHCb实验中观测到的B介子衰变为矢量介子，为利用量子信息理论方法研究粒子物理现象提供了理想实验室。本文聚焦于产生一对$\it\Phi$介子的衰变，以考察该系统自旋关联中纠缠的存在，并量化其所导致的Bell不等式违反程度。结果表明，现有LHCb数据能够在两种情形下均以超过5σ阈值的显著性观测到纠缠和Bell不等式违反。这证明导致B介子衰变的强相互作用和电弱相互作用充当了纠缠源，并体现了高能现象的量子力学本质。文中特别关注对漏洞的评估：即实验装置中可能使Bell检验结果失效的缺陷。
英文摘要：
The decays of the $B$ meson into vector mesons, observed at the LHCb experiment, provide an ideal laboratory to investigate particle physics phenomena with quantum information theory methods. In this article, we focus on the decays yielding a pair of $\itΦ$ mesons to investigate the presence of entanglement in the spin correlations of the system and quantify the amount of Bell inequality violation it entails. Our results show that the present LHCb data allows access to entanglement and to the Bell inequality violation with a significance exceeding the 5$σ$ threshold in both the cases. This demonstrates that the strong and electroweak interactions responsible for the $B$ meson decay act as a source of entanglement and the quantum mechanics nature of high-energy phenomena. Particular attention is paid to the assessment of loopholes: deficiencies in the experimental setup which could invalidate the results of the Bell test.
