在$ϕ$ -工厂中纠缠中性K介子系统时间反演对称性的直接检验

Direct test of time-reversal symmetry in the entangled neutral kaon system at a $ϕ$-factory

摘要:

我们提出了一种新的方法来执行一个直接的T(时间反演)对称性测试的中性K介子系统,独立于任何CP和/或CPT对称性测试。这是基于合适的过渡概率的比较,其中所需的交换中<->出状态为一个给定的过程中获得利用中性K介子对在$ϕ$ -工厂的爱因斯坦-波多尔斯基-罗森相关。在两个衰变之间的时间分布中,我们比较了由时间有序衰变$(\ell^-,ππ)$定义的参考跃迁与由$(3π^0, \ell^+)$定义的T共轭跃迁。通过使用该比较和其他T结合比较,DA $Φ$ NE的KLOE-2实验可进行显著性检验。

英文摘要:

We present a novel method to perform a direct T (time reversal) symmetry test in the neutral kaon system, independent of any CP and/or CPT symmetry tests. This is based on the comparison of suitable transition probabilities, where the required interchange of in <-> out states for a given process is obtained exploiting the Einstein-Podolsky-Rosen correlations of neutral kaon pairs produced at a $ϕ$-factory. In the time distribution between the two decays, we compare a reference transition like the one defined by the time ordered decays $(\ell^-,ππ)$ with the T -conjugated one defined by $(3π^0, \ell^+)$. With the use of this and other T conjugated comparisons, the KLOE-2 experiment at DA$Φ$NE could make a significant test.
