Description

The sPHENIX detector at the Relativistic Heavy Ion Collider is designed to measure high momentum probes of the quark-gluon plasma such as jets. Jet measurements in heavy-ion collisions require subtraction of the large underlying event consisting of low momentum particles produced from the QGP medium. While subtraction techniques can remove the average size of the background, localized fluctuations can result in an over- or under-subtraction of the underlying event. This effect leads to an increase in the jet energy resolution, which can be understood through the size of the underlying event fluctuations. This poster presents a study of the expected jet energy resolution from both detector effects and underlying event fluctuations using simulations of the sPHENIX detector.
