Recent advances in conformal field theory have reformulated collider jet substructure as the study of energy correlators. In this talk, I will introduce energy correlator observables and the advantages of their use to probe the quark-gluon plasma (QGP) produced in heavy-ion collisions. I will discuss the recent measurement of the two-point energy correlator (EEC) in Pb-Pb collisions at the Large Hadron Collider and introduce the first jet substructure observable that corrects for the leading-order effects of selection bias due to energy loss —a longstanding challenge in interpreting jet substructure measurements in heavy-ion collisions. Finally, using the light-ray operator product expansion (OPE), I will show that nuclear modifications of the EEC in both Pb-Pb and p-Pb collisions are driven by an enhanced twist-4 contribution. These findings open new avenues for a more precise understanding of nuclear modifications in jet substructure.
