AI 中文摘要
量子信息概念为研究粒子相互作用的理论结构提供了新方法,尤其已证明散射与衰变过程中的量子纠缠极值与粒子的对称性及特征性质相关。我们聚焦于一个更具体的问题:散射过程中产生的纠缠熵最小化是否与违反整体对称性或选择规则的相互作用的抑制存在系统性关联。我们推测,当新相互作用开启对称性破缺散射道时,纠缠熵的最小化可选择出对称性保持点。我们通过考虑超出标准模型(BSM)且违反整体对称性或对应选择规则的相互作用,包括轻子数破缺、重子数破缺、轻子味破缺及味改变中性流,来探究该推测的合理性。我们证明,当对称性破缺相互作用开启与对称性保持 sector 正交的末态 sector 时,对称性保持点成为纠缠熵的局域极小值。我们的结果支持纠缠熵最小化可作为抑制与对称性破缺相互作用相关的 BSM 现象的通用信息论原理的可能性。
英文摘要
The concept of quantum information has provided new ways to investigate the theoretical structure of particle interactions. In particular, it has been shown that extrema of quantum entanglement in scattering and decay processes can be related to symmetries and characteristic properties of particles. We focus on a more specific question: whether the minimization of entanglement entropy generated in scattering processes is systematically related to the suppression of interactions that violate global symmetries or selection rules. We conjecture that the minimization of the entanglement entropy can select the symmetry-preserving point when a new interaction opens a symmetry-violating scattering channel. We investigate the plausibility of this conjecture by considering interactions beyond the Standard Model (BSM) that violate global symmetries or the corresponding selection rules, including lepton number violation, baryon number violation, lepton flavor violation, and flavor-changing neutral currents. We show that, when symmetry-violating interactions open final-state sectors that are orthogonal to the symmetry-preserving sector, the symmetry-preserving point becomes a local minimum of the entanglement entropy. Our results support the possibility that the minimization of entanglement provides a common information-theoretic principle underlying the suppression of BSM phenomena relevant to symmetry-violating interactions.
