论文摘要
使用最大的$ j/ψ$和$ψ（3686）$数据样本在Besiii实验中收集的数据样本，在其量子纠缠系统中生成了超子抗hyperon对。已经观察到了超子的极化，这使得可以精确地测量Hyperon和Antiperon的衰减参数。估计CP保护可观察物，这对于测试标准模型很重要。同时，已经测量了与超子对产生相关的分支分数和角度分布。
Using the largest $J/ψ$ and $ψ(3686)$ data samples collected at the BESIII experiment, the hyperon anti-hyperon pairs are generated in their quantum entangle system. The polarization of hyperon has been observed, which makes it possible to measure the decay parameters of hyperon and anti-hyperon precisely. The CP conservation observables have been estimated which is important to test the Standard Model. In the meanwhile, the branching fractions and angular distributions related to hyperon pair production have been measured.
