Title: Energy correlators in the nuclear matter
Abstract: Energy correlators have re-emerged as observables capable of probing the properties of QCD at high energies, providing new tools to study the structure of jets from a well posed QFT framework. In the vacuum, they have been used to extract the strong coupling constant and the anomalous scaling of the leading twist QCD operators. However, in the presence of a background medium, the behavior of these observables is still not fully understood. In this talk, I will present some recent developments in the description of energy-energy correlators in the context of collisions involving nuclei. I will first discuss the general form of the EEC in AA collisions, and then argue that some of these features can be contaminated by the hydrodynamical response of the bulk media. In contrast, by looking at pA collisions, I will argue that the medium effects can be more cleanly extracted, once the non-perturbative sector is also taken into account.
