粒子衰变中的三体纠缠

Three-body Entanglement in Particle Decays

Kazuki Sakurai, Michael Spannowsky

AI总结:

本文将量子纠缠研究拓展至三体粒子衰变,利用 concurrence 与一夫一妻性质分析三粒子关联,为检验标准模型偏差及重费米子、强子衰变研究提供新途径。

摘要:

长期以来,量子纠缠一直是理解量子力学的基础支柱,而相关研究主要集中在双粒子系统上。我们将纠缠研究扩展到三体衰变领域,从而对量子关联提供更复杂的理解。通过利用纠缠度量 concurrence(纠缠并发度)原理和一夫一妻性质,我们为三粒子系统引入了一种新方法。研究结果凸显了研究偏离 Standard Model(标准模型)现象的潜力,并强调了其在粒子现象学中的重要性。这项工作为通过多粒子量子纠缠获得粒子物理的新认识铺平了道路,尤其是在重费米子和强子衰变中。

英文摘要:

Quantum entanglement has long served as a foundational pillar in understanding quantum mechanics, with a predominant focus on two-particle systems. We extend the study of entanglement into the realm of three-body decays, offering a more intricate understanding of quantum correlations. We introduce a novel approach for three-particle systems by utilising the principles of entanglement monotone concurrence and the monogamy property. Our findings highlight the potential of studying deviations from the Standard Model and emphasise its significance in particle phenomenology. This work paves the way for new insights into particle physics through multi-particle quantum entanglement, particularly in decays of heavy fermions and hadrons.
