Description
This talk presents the latest result on the energy-energy correlator using the archived ALEPH e+e- data taken at the LEP at a center of mass energy of sqrt(s) = 91.2 GeV. The energy-energy corrector presents a different way to study QCD concerning other approaches utilizing jets and (sub)structures, garnering recent increased interest in this observable in hadronic collision systems at the LHC and RHIC. It allows a natural separation of length scales, which probe various aspects of QCD. In addition to studying the smaller scale behavior where most of the focus in the field has been thus far, thanks to the unique topology of e+e- collisions, the energy-energy correlators for nearly back-to-back particles are measured experimentally for the first time. They are also compared with predictions from various generators. We also discuss potential extensions and synergy with future studies at EIC and FCC.
