Description
Energy-Energy Correlators (EEC) probe the dynamics of the quark gluon plasma (QGP) by mapping the final-state energy by mapping the angular distribution of final-state energy. At the Relativistic Heavy Ion Collider (RHIC), $\sqrt{s_{NN}} = 200$ GeV collisions provide a complementary kinematic regime to the LHC, but jet substructure measurements are challenged by lower jet energies and a large soft background. The Whole Event Energy Correlator (wEEC) extends EEC measurements to the full dijet system, capturing both small- and large-angle correlations.
In this talk, we present a Monte Carlo feasibility study of the wEEC and single jet EEC measurement at RHIC energies focusing on background subtraction methodology. We use PYTHIA embedded in a hydrodynamic background to model the heavy-ion environment. By incorporating jet quenching, we study how medium-induced modifications affect the performance of background subtraction and the reconstruction of correlators. These studies explore subtraction and reconstruction methods providing a foundation for future wEEC measurements at RHIC.
