在这篇快报中，我们强调，在壳Z玻色子衰变产生的电荷通量不对称性，是标准模型（SM）中电弱反常的宏观体现。我们提出，可利用电荷关联函数对其进行干净观测，这为前后不对称性测量提供了新的表述形式，特别适用于强子衰变的精确研究。利用存档的DELPHI数据，我们首次测量了强子上电磁电荷通量的单点电荷关联函数，并清晰观测到了 underlying 反常的宏观印记。我们的分析表明，电荷关联函数作为精确电弱观测量的潜力，并推动人们为解决强子不对称性测量中长期存在的张力而付出新的努力。
英文摘要
In this Letter, we emphasize that asymmetries in charge flux produced in the decays of on-shell Z-bosons provide a macroscopic manifestation of electroweak anomalies in the Standard Model (SM). We propose that these can be cleanly observed using charge correlators, providing a new formulation of forward-backward asymmetry measurements that is particularly well suited for precision studies of hadronic decays. Using archival DELPHI data, we perform a first measurement of the one-point charge correlator of electromagnetic charge flux on hadrons, and cleanly observe the macroscopic imprint of the underlying anomaly. Our analysis illustrates the potential of charge correlators as precision electroweak observables, and motivates a renewed effort to resolve longstanding tensions in hadronic asymmetry measurements.
