Particle Correlations in Jets

Year: 2026

Type: article

Abstract: We study particle correlations in high energy jets by comparing the measured energy-energy correlator with that constructed from two individual energy flows with respect to the jet axis. This comparison demonstrates that the genuine correlations are stronger at moderate or large angles across all jet energies, indicating that they are coming from correlated splitting. Meanwhile, at small angles, they increase with jet energy, exhibiting a peculiar pattern that can be used to explore jet energy loss in heavy-ion collisions. This method will provide a unique tool to disentangle different physics by comparing the genuine correlations in jet energy-energy correlators between heavy-ion collisions and proton-proton collisions.
