sPHENIX Minimum Bias Trigger Efficiency as a function of Jet p_T in pp at √s = 200 GeV

The sPHENIX experiment at RHIC is designed to explore the properties of the quark-gluon plasma through precision measurements of jets, heavy flavor, and quarkonia. As part of this modern collider experiment, the calorimeter system, consisting of electromagnetic and hadronic calorimeters, provides full azimuthal acceptance and pseudorapidity coverage of |η| < 1.1. For analyses involving absolute cross sections of jet observables, a key correction involves the efficiency of the minimum bias (MB) trigger. This trigger is based on the minimum bias detector which is positioned along the beam line, and covers the pseudorapidity range 3.51 < |η| < 4.61 in the far forward and backward regions. We evaluate the MB trigger efficiency as a function of jet transverse momentum using both Pythia Monte Carlo simulations and √s = 200 GeV proton-proton collision data collected during Run-24. We observe that the MB efficiency is inversely correlated with high-p_T jet production at midrapidity due to finite collision energy, as expected. This talk will review this correction, and presents the analysis of the MB trigger efficiency in Run-24.
