data at 91.2 GeV

This talk presents the latest result on 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. Recently, there has been increased interest in studying the energy-energy correlator in hadronic collision systems at the LHC and RHIC. It presents a different way to study QCD concerning other approaches utilizing jets and (sub)structures. The observable allows a natural separation of length scales, which probe different 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 generations. We also discuss potential extensions and future aspects.
