Description
N-point energy correlators have recently gained prominence in the field of high energy particle and nuclear physics due to features that make the observable a unique probe of multi-scale QCD evolution. Several experimental collaborations have either measured the 2-point energy-energy correlator (EEC), an observable that quantifies the energy product weighted particle pairs within a jet or within a full collider event at a fixed opening angle. This has direct connection to conformal theory approaches that separates the different regimes within the observable as a function of the opening angle. In this talk, I will start with the the recent CMS measurement of inclusive jet EECs in heavy ion collisions and walk through the different theory and phenomenology studies aimed at understanding the data. We close the talk by discussing the next steps in evaluating scale dependent QCD evolution at various temperatures in proton-proton, proton-Ion and Ion-Ion collisions.
