We introduce a nonperturbative model that allows us to describe the energy-energy correlator in the entire angular region of the current experiments. Our results for proton-proton collisions show excellent agreement with CMS and ALICE data over a wide range of jet transverse momenta. For proton-nucleus collisions, we include modifications from the nuclear medium, and our predictions align well with the trends observed in recent ALICE measurements.</p>American Physical Society2025-06-0110632241Physical Review Letters134250031-9007https://doi.org/10.1103/96xh-bd1w1945471National Science Foundation
