AI 中文摘要
我们利用1994年和1995年在质心系能量√s=91.2 GeV的LEP-1上采集的DELPHI开放数据，首次测量了单电荷关联器——强子末态中电荷的角通量。经探测器效应修正后的数据呈现出清晰的sin(2θ)调制，这与Z耦合的手征结构在末态中留下的宇称破缺强子电荷流一致。该测量证明了该可观测物理量的实验可行性，并建立了控制相关探测器效应的策略，从而推动了测量电荷通量可观测物理量的新计划。本说明记录了支持配套实验论文及理论-实验联合快报的实验细节。
英文摘要
We present the first measurement of the one-point charge correlator, the angular flux of electric charge in hadronic final states, using DELPHI Open Data collected at LEP-1 at $\sqrt{s} = 91.2$~GeV during 1994 and 1995. The data, corrected for detector effects, exhibit a clear $\sin(2θ)$ modulation, consistent with the parity-violating hadronic charge flow that the chiral structure of the $Z$ couplings imprints on the final state. The measurement demonstrates the experimental feasibility of the observable and establishes strategies for controlling associated detector effects, thereby motivating a new program to measure charge-flux observables. This note documents the experimental details supporting the companion experimental paper and the joint theory--experiment Letter.
