量子SMEFT层析成像:顶夸克对

Quantum SMEFT tomography: top quark pair

Luca Mantani

摘要:

近年来,高能粒子物理学界对量子信息的研究兴趣日益浓厚。在粒子对撞机(如欧洲核子研究中心的大型强子对撞机(LHC))上建立纠缠存在的可能性是一个新颖而激动人心的研究方向,它提供了通过使用最重的基本粒子(顶夸克)将量子力学推向极限的机会。考虑到这一点,我们建议使用量子纠缠的测量来探测基本相互作用的行为,并在标准模型有效场论范式内寻找高能量的新物理。最近的建议,以测量在大型强子对撞机产生的顶夸克对纠缠的启发,我们研究如何存在的基本粒子之间的新的相互作用修改标准模型的期望。通过分析计算,我们揭示了一个非平凡的模式的影响取决于运动学相空间配置。

英文摘要:

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.
