 tract: More than twenty-five years after LEP shut down\, its archival data
  remain a remarkably rich testing ground for modern ideas in high-energy p
 hysics. In this talk\, I present measurements of energy and charge correla
 tors with archival LEP data\, a class of observables from modern quantum f
 ield theory that connect real-world measurements directly to the structure
  of the theory. The energy–energy correlator reveals conformal scaling a
 nd its breaking at the emergent scale of QCD where quarks and gluons becom
 e hadrons. The charge correlator is a macroscopic manifestation of the ele
 ctroweak anomaly\, providing a new formulation of the forward–backward a
 symmetry. Measured for the first time in both electric charge and the bott
 om-flavor quantum number\, it opens a new route to precision measurements 
 of the weak mixing angle and to investigating the longstanding tension in 
 the bottom-quark forward–backward asymmetry. These measurements illustra
 te how ideas from formal theory can be turned into experimental observable
 s that address open questions in high-energy physics\, while demonstrating
  the scientific potential of open data and open science.Speaker: Jingyu Zh
 ang (张竞予) is an experimental particle and nuclear physicist. He rece
 ived his bachelor's degree from Beihang University and his Ph.D. from the 
 University of Illinois Chicago. Following his Ph.D.\, he was a postdoctora
 l researcher at Florida State University and a Distinguished Researcher at
  the LHC Physics Center at Fermilab. His earlier work centered on CMS data
  analysis\, with particular expertise in QCD\, jets\, and statistical meth
 ods\, and he also made major contribution to CMS detector operations and u
 pgrades. He is currently a postdoctoral researcher at Vanderbilt Universit
 y\, focusing on the analysis of archived LEP data and on developing statis
 tical tools for global analyses of collider data.\n\nhttps://indico.ihep.a
