Description
The sPHENIX detector at the BNL Relativistic Heavy Ion Collider (RHIC) benefits from the extensive advances of the Large Hadron Collider (LHC) and Electron-Ion Collider (EIC) detector R&D. The combination of electromagnetic calorimetry, hermetic hadronic calorimetry, precision tracking, and the ability to record data at high rates without trigger bias enables pioneering measurements of jets, jet substructure, and jet correlations. Jet observables are a particularly useful probe of the Quark Gluon Plasma (QGP) formed in heavy-ion collisions since the hard scattered partons that fragment into final state jets are strongly quenched through interactions with the medium they traverse. These measurements will have a kinematic reach that not only overlaps those performed at the LHC, but extends them into a new, low-pT regime where quenching effects are large. Thus the sPHENIX physics program, starting in 2023, can answer fundamental questions about the parton energy loss process, and the underlying nature of the QGP. This talk will give an overview of the status of jet reconstruction and performance within sPHENIX, and the envisioned jet physics program.
