Description
In recent years, there has been a resurgence of interest in energy-energy correlators (EECs) for the study of hadronic collisions at both the LHC and RHIC ranging from small to large systems. Measurements of EECs of particles within jets offer a clear separation of scales that is useful for studying both perturbative and non-perturbative QCD in the collinear limit as well as the transition between these two regimes. In the $e^{+}e^{-}$ environment, measurements of EECs can be performed using all particles in the event, allowing for the back-to-back (or Sudakov) limit to also be investigated. This talk presents a high precision fully-corrected EEC results from the archived ALEPH $e^{+}e^{-}$ data taken at LEP at $\sqrt{s}$ = 91.2 GeV. The data are compared to archived PYTHIA 6 MC produced by the ALEPH collaboration as well as theoretical prediction with Next-To-Next-To-Next-To Leading Log resummation in the collinear limit and Next-To-Next-To-Next-To-Next-To Leading Log in the Sudakov limit, showing excellent agreement with data. This measurement allows for precision tests of QCD to be performed in the relatively unexplored Sudakov limit of QCD.
