Abstract
Energy-energy correlators (EECs), which are energy-weighted cross-sections of particle pairs, offer incisive probes into QCD dynamics, across the full scale of jet evolution, by separating energy scales in the jet fragmentation through the angular distance of the resulting particle pairs. Charged EECs probe the energy flux carried by pairs of the same or opposite electric charges. The interplay between energy distribution and charge conservation enables charged EECs to provide novel constraints on hadronization mechanisms. We present the first measurements of two-point charged energy correlators of inclusive jets in pp collisions at √s = 5.02 TeV using the ALICE detector, and compare them with hadronization models to investigate different confinement mechanisms. We also present measurements in p-Pb collisions, examining cold nuclear matter effects on jet evolution.
