论文摘要
Leggett的不平等是对双方相关性的限制，该相关性接受了某些类型的非局部性。现有测试主要集中在电磁系统上，其中假定测量设备是投影和锋利的。但是，在本质上，有一些相互作用不遵守光子的相同保护法，并且由于基本的物理原理，实际测量可能会遭受不可避免的不确定性。在这项工作中，我们概括了Leggett的不平等，以结合未分离和/或有偏见的测量结果。发现自然界中的平等违规行为提供了对超子自旋的UNSHARP测量的自发实现。获得了以不对称参数为特征的超子衰减的精细结构化leggett不等式，并且发现其违规行为可以通过在实验中尚未获得的数据观察到，例如besiii和belle。
The Leggett inequality is a constraint on the bipartite correlation that admits certain types of non-localities. Existing tests mainly focused on the electromagnetic systems where measurement apparatus are assumed to be projective and sharp. However, in nature there are interactions that do not obey the same conservation laws for photon, and the actual measurements may subject to unavoidable uncertainties due to the fundamental physical principles. In this work, we generalize the Leggett inequality to incorporate the measurements that are unsharp and/or biased. It is found that the parity violation in nature provides a spontaneous implementation of an unsharp measurement for the spin of hyperon. A fine structured Leggett inequality for hyperon decays characterized by the asymmetry parameters is obtained and its violation is found which could be observed with the yet obtained data in experiment, like BESIII and Belle.
