Description
The sPHENIX experiment is a next-generation collider detector at RHIC designed for rare jet and heavy flavor measurement in a variety of hadronic collision systems. The experiment includes large-acceptance, electromagnetic (EMCal) and hadronic (HCal) calorimeter systems, along with a very high-rate data acquisition plus trigger system. In RHIC Run-24, sPHENIX sampled 107/pb of p+p collision data at 200 GeV using efficient high-p$_T$ jet and photon triggers. This dataset represents a major increase in the luminosity times acceptance compared to previous measurements for this collision energy, along with the first HCal at mid-rapidity at RHIC for measuring the contribution from neutral hadrons to jets and to the photon isolation energy. This talk will report preliminary measurements of hard scattering processes, including reconstructed jets and isolated photons, over an extensive range of initial parton kinematics. The results, which can provide constraints on the proton PDFs in an extreme region up to Bjorken-x ~ 0.7, will also include comparisons to modern pQCD calculations.
