论文摘要
近年来，对量子信息研究的兴趣在高能粒子物理界内增长。在粒子山脉界面上建立纠缠的可能性，例如CERN的大型强子对撞机（LHC），是一个新颖而激动人心的研究方向，为使用最重的基本粒子提供了将量子力学推向其极限的机会：最高的夸克。考虑到这一点，我们建议使用量子纠缠的测量值来探测基本相互作用的行为，并在标准模型有效田间理论范式中搜索高能量的新物理学。受到最近提案测量LHC产生的顶级夸克对纠缠的启发，我们研究了基本粒子之间新相互作用的存在如何修改标准模型期望。通过执行分析计算，我们根据运动学相空间构型提出了一种非平凡的效果模式。
In recent years, an interest in the study of quantum information has grown within the high-energy particle physics community. The possibility to establish the presence of entanglement at particle colliders, such as the Large Hadron Collider (LHC) at CERN, is a novel and thrilling research direction, offering the opportunity to push quantum mechanics to its limits by using the heaviest fundamental particle: the top quark. With this in mind, we propose to use measurements of quantum entanglement to probe the behaviour of fundamental interactions and to search for New Physics at high energy within the Standard Model Effective Field Theory paradigm. Inspired by recent proposals to measure entanglement of top quark pairs produced at the LHC, we examine how the existence of new interactions between fundamental particles modify the Standard Model expectations. By performing analytical calculations, we unveil a non-trivial pattern of effects depending on the kinematical phase space configurations.
