Description
sPHENIX is a new experiment at the Relativistic Heavy Ion Collider (RHIC), designed with large-acceptance, hermetic EM and hadronic calorimeters. One of the main goals of the sPHENIX experiments is the measurement of jets and their substructure in heavy ion collisions as a probe of the QGP at RHIC. Since jets in heavy ion collisions sit on top of large fluctuating backgrounds, these must be understood to carry out a precision program of jet physics.
This talk reports a detailed characterization of the underlying event and jet background fluctuations at RHIC using 200 GeV Au+Au collision data collected with the sPHENIX calorimeter system during its 2023 commissioning run. The characterization uses several approaches: unbiased sampling of calorimeter window areas and random cones, as well as methods sensitive to jet reconstruction effects such as embedding high-pT probes from data or simulation into recorded minimum-bias Au+Au data. The non-Poissionian background fluctuations for several jet background subtraction methods are also investigated. Lastly, we present highlights of the envisioned sPHENIX jet physics program.
