论文摘要
在先前的工作中，“弹性$ e^+ e^ - $ qed中的自旋相关性”（Yongram，2018年），纠缠电子和正电子的自旋相关性作为电子 - positron散射的新兴粒子（也称为Babha散射），在QED中计算在树级别。在尝试复制作者的作品时，我们发现了不同的结果。在这项工作中，我们显示了完全（初始和最终极化状态）的计算，以及部分（仅是最终极化状态）在所有能量下电子散射散射的极化概率振幅。尽管扬兰（Yongram）声称违反克劳瑟·霍恩（Clauser-Horne）不平等（CHI）在所有提及的情况下都发生在所有能量，但对于完全极化的散射，我们发现违反了CHI的速度$β\ gtrsim 0.696 $，包括高能量限制，包括高能量限制，支持QED协议和量子力学基础之间的协议之间。但是，对于最初的非极化颗粒，我们发现没有违反CHI的行为。
In the previous work, "Spin correlations in elastic $e^+ e^-$ scattering in QED" (Yongram, 2018), spin correlations for entangled electrons and positrons as emergent particles of electron-positron scattering (also known as Bhabha scattering) were calculated at tree level in QED. When trying to reproduce the author's work, we have found different results. In this work, we show the calculation for fully (initial and final polarized states) and partially (just final polarized states) polarized probability amplitudes for electron-positron scattering at all energies. While Yongram claims that violation of Clauser-Horne inequality (CHI) occurs at all energies for both mentioned cases, for fully polarized scattering we found violation of the CHI for speeds $β\gtrsim 0.696$, including the high energy limit, supporting the agreement between QED and foundations of quantum mechanics. However, for initially unpolarized particles we found no violation of the CHI.
