CMS track reconstruction performance during Run 3

Key Points

• The aim is to assess the performance of track reconstruction methods used in the CMS experiment during Run 3 at the LHC.
• Performance measured using both simulation and real collision data from LHC Run 3.
• Focus on Silicon Pixel detector's role in track reconstruction accuracy.
• Comparative analysis between data and simulation on essential track quantities.
• Evaluation of efficiencies at both high level trigger and through tag-and-probe techniques.
• Detailed performance metrics for track reconstruction in simulation and actual data are provided.
• High level trigger efficiencies revealed significant accuracy in detecting charged particle tracks.
• Tag-and-probe techniques validated effective measurement of track parameters.
