Description
The sPHENIX detector at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) is a state-of-the-art jet and heavy flavor physics detector that includes hadronic calorimetry at mid-rapidity for the first time at RHIC. During the p+p $\sqrt{s}$ = 200 GeV run in 2024, 107 pb$^{−1}$ of pp collisions were sampled using high $p_T$ jet triggers. The presence of the Quark Gluon Plasma (QGP) in heavy ion collisions impacts jet substructure, giving insight into the nature of the QGP itself. Measurements of jets and jet structure in p+p collisions provide an important baseline for these measurements in heavy ion collisions. This poster will discuss initial jet substructure measurements using only calorimetric information by first clustering calorimeter towers into Anti-$k_T$ R = 0.2 ”constituent” jets before reclustering them into Anti-$𝑘_𝑇$ R = 0.4 jets for substructure study through use of the soft-drop algorithm. We will show the current status of this study, in both simulation and p+p data.
