Energy-energy correlators in jets across collision systems and parton flavors

Nuclear Experiment 2025-10-21 v1

Abstract

The two-point energy-energy correlator (EEC) is a novel jet substructure observable probing the correlation of energy flow within jets. In these proceedings, three EEC measurements performed by the ALICE Collaboration are reported. First is a finalized measurement in proton-proton collisions, where the angular dependence of the EEC cross-section shows a separation of the perturbative and non-perturbative regimes. The first EEC measurement is reported in heavy-flavor jets, tagged via a fully-reconstructed D0^0 meson. Here, comparison to inclusive pp jets provides insights into the flavor dynamics of QCD fragmentation and hadronization. Finally, the first measurement of EECs in p-Pb collisions is presented. By comparing the results to pp, modifications in jet evolution caused by the presence of a cold nuclear medium can be studied.
