Abstract

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 √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.
