Measurements of the Two-Point Energy-Energy Correlator in pp Collisions √s = 510 GeV at STAR

ORAL

Abstract

In the collinear limit, Energy-Energy Correlators (EEC) have been used to probe the substructure of jet in e-e+ and pp collisions. This presentation will discuss the measurement of EECs in pp collisions at √s = 510 GeV with a focus on understanding the transition from the perturbative early time fragmentation to the non-perturbative hadronization at later times. The experimental

definition of the EEC in this presentation is constructed from charged hadrons in inclusive mid-rapidity (| η | < 1) jets reconstructed at the Solenoidal Tracker at RHIC (STAR). The EEC is measured for several kinematic regions that are defined by the jet transverse momentum (pT) as well as the angular (RL) and azimuthal (△φ) separation between charged-track pairs.
