Abstract
Jet substructure is a powerful tool for testing QCD in elementary particle collisions. The two-point energy-energy correlator (EEC), defined as the energy-weighted cross section of particle pairs inside jets, is a novel jet-substructure observable probing the correlation of energy flow within jets. In pp collisions, the angular dependence of the EEC cross section shows a distinct separation of the perturbative and non-perturbative regimes, revealing the partonic dynamics of jet formation and the confinement of partons into hadrons. In these proceedings, we present measurements of the EECs for inclusive jets in p-Pb collisions at √sNN = 5.02 TeV. By comparing our results to a measured pp baseline, we study jet modification to probe for cold nuclear-matter (CNM) effects. Understanding modifications due to CNM effects is vital to interpreting EEC results in Pb–Pb collisions and separating hot and cold nuclear-matter effects.
