Description
The sPHENIX experiment operating at RHIC aims to make high precision measurements of jets and heavy flavor observables for a wide selection of nuclear collision systems. Its tracking system is composed primarily of 4 subsystems that work in tandem to reconstruct the path of ionizing radiation through the detector geometry. Starting with the innermost detector and moving radially outward, the MVTX yields precise vertexing information and the finest position resolution, the INTT provides precise timing resolution on the order of tens of nanoseconds to associate tracks with the bunch crossing which produced them, the TPC works as the primary tracker which gives the majority of track clusters and is the foundation of the momentum resolution obtained, and the TPOT helps correct for static and dynamic space charge distortions in the TPC. It is crucial that we are able to understand the acceptance and efficiency of this tracking system as a whole in order to produce meaningful physics results. We employ a tag-and-probe scheme applied to several decay modes as a means of using data to determine the efficiency of the sPHENIX tracking system. Additionally, we compare the results of this measurement with a large truth-associated simulated sample of the same decay modes in order to validate our observations.
