sPHENIX Tracking performance and Related Physics Studies

The sPHENIX detector at Relativistic Heavy Ion Collider (RHIC) is the state of the art experiment recently built at Brookhaven National Laboratory. It has a broad experimental QCD physics program that is highlighted by jets, their substructure, and open and closed heavy flavor production. To measure these observables, the sPHENIX tracking system is composed of vertex detector based on monolithic active pixel sensors (MVTX), a silicon strip detector - the intermediate tracker (INTT), and a compact time projection chamber (TPC) designed to provide continuous readout. Track reconstruction is a key element for the success of sPHENIX physics program.

This presents challenges due to the large track density environment present in central heavy ion collisions, the high luminosity environment that RHIC is providing, and the high rate readout model that sPHENIX is collecting data with. This talk will present the physics performance of the current track reconstruction and present the status of measurements for bulk particle production and open charm sector.
