الملخص	Time-of-Flight (ToF) particle identification measures the time taken for a particle to travel a known distance, enabling determination of the particle's velocity and mass. This complementary technique to Cherenkov and ionization energy loss provides robust particle separation across wide momentum ranges in modern detectors.	Track reconstruction is the process of identifying and measuring the trajectories of charged particles through a detector, providing momentum and impact parameter information essential for particle identification, vertex reconstruction, and physics analysis in high-energy physics experiments.
