Early results from the sPHENIX calorimeter jet program

The sPHENIX detector at the Relativistic Heavy Ion Collider (RHIC) is designed to study the small scale structure of the quark-gluon plasma (QGP) created in heavy ion collisions. Jets, produced in hard scatterings early in the collisions, provide an ideal probe for the full evolution of the QGP. The sPHENIX experiment includes large acceptance, electromagnetic (EMCal) and hadronic (HCal) calorimeter systems, along with a high-rate data acquisition plus trigger system, making it an excellent detector for measuring jets. In RHIC Run-23 sPHENIX began commissioning and collected a small sample of calorimeter data in Au+Au collisions. This dataset allows for measurements of the bulk properties of the QGP, important for understanding the soft, fluctuating underlying event in jet events. In RHIC Run-24, sPHENIX sampled 107/pb of p+p collision data with high-pT jet and photon triggers. This dataset allows for high precision baseline measurements for future jet quenching measurements in Au+Au collisions. This talk will present the status of calorimeter jet measurements in these datasets.
