Radiation damage effects on the CMS tracking system in Run 3

Reconstructing charged particles with high precision is one of the core requirements of modern High Energy Physics (HEP) experiments, and silicon detectors provide the technology to achieve this. Due to their proximity to the interaction point, silicon trackers must withstand significant amounts of radiation, which reduces the charge collection efficiency, degrades tracking resolution, and lowers signal-to-noise ratios. With the high luminosities for current data-taking at the LHC, accurately modeling these radiation-induced effects in silicon sensors is essential to preserve the precision and efficiency of these detectors. In this study, we focus on comparing leakage current evolution under Run 3 conditions in data and simulation, and understanding the prospects for the tracking detector performance through the end of Run 3.
