Calibrated Cosmic Muon simulations for the sPHENIX Hadronic Calorimeters

The sPHENIX detector at BNL's Relativistic Heavy Ion Collider (RHIC) will start data taking in 2023 and seeks to understand the microscopic properties of the Quark-Gluon Plasma(QGP), by performing high precision measurements of jets and heavy flavor observables. Critical to full jet reconstruction is the sPHENIX hadronic calorimeter (HCal) system, which will be the first calorimetric hadronic measurements made at RHIC. To do this, the HCal needs to be properly calibrated prior to and during the data taking to measure the energy deposition of jets. This talk will present the GEANT4 study with a cosmic muon generator with a realistic zenith angle and energy distribution to investigate the possibility of using cosmic muon events as a calibration source for the hadronic calorimeters (HCal's) when the full sPHENIX apparatus is in its data-taking position.
