Abstract

In this Letter, we study the collinear limit of the Energy-Energy Correlator (EEC) in single-inclusive jet production in proton-proton (pp) and proton-nucleus (pA) collisions. We introduce a non-perturbative model that allows us to describe the EEC in the entire angular region of the current experiments. Our results for pp collisions show excellent agreement with CMS and ALICE data over a wide range of jet transverse momenta. For pA collisions, we include modifications from the nuclear medium, and our predictions align well with the trends observed in recent ALICE measurements.
