高能物理中自旋的非定域关联

Nonlocal Correlation of Spin in High Energy Physics

Chen Qian, Jun-Li Li, Abdul Sattar Khan, Cong-Feng Qiao

摘要:

非定域性是量子理论的一个重要特征,它反映在纠缠系统对贝尔不等式的违反上。电磁场和无质量量子之外的实验检验对于理解不同量子相互作用中的非定域性具有重要意义。在这项工作中,我们建立了一个推广的Clauser-Horne不等式,特别适用于高能物理过程,这是量子力学干涉自由。我们发现,在赝标夸克偶素排他衰变为纠缠$Λ\barΛ$对的过程中,不等式可以被打破,并且在高能实验中得到验证,如BES III或BELLE II。

英文摘要:

Nonlocality is a key feature of quantum theory and is reflected in the violation of Bell inequalities for entangled systems. The experimental tests beyond the electromagnetism and massless quanta are of great importance for understanding the nonlocality in different quantum interactions. In this work, we develop a generalized Clauser-Horne inequality pertaining especially to the high energy physics processes, which is quantum mechanical intervene free. We find, in the process of pseudoscalar quarkonium exclusive decay to entangled $Λ\barΛ$ pairs, the inequality could be violated and is verifiable in high energy experiments, like BES III or BELLE II.
