Description
The proposed sPHENIX detector at RHIC will allow state-of-the-art measurements of jets and jet correlations, making using of recent technological and conceptual advances. The kinematic reach of these measurements will overlap with those made at the LHC by taking advantage of the increased luminosity due to accelerator upgrades and the sPHENIX acceptance and rate capability. Particle jets, formed when a hard scattered parton fragments and then hadronizes into a spray of particles, were proposed as a probe of the Quark Gluon Plasma (QGP) formed in heavy-ion collisions. As these partons traverse the QGP, they lose energy to the medium, an effect called "jet quenching". To answer fundamental questions about parton energy loss and the microscopic nature of the QGP, we need to characterize both the medium induced modification of the jet fragmentation pattern and the correlation of the lost energy with the jet axis. Observables centered around gamma-jet correlations are especially useful as the photon kinematics are more tightly correlated with the hard scattered parton. In addition, there are other observables such as jet fragmentation functions and jet shape measurements, which require the precise tracking and calorimetry that sPHENIX will provide. We will show the performance of jet and gamma-jet observables with the improved simulation framework developed for understanding the performance of the new detector.
