Particle Identification capabilities of ALICE Inner Tracking System

The Inner Tracking System is a silicon pixel detector designed with very a high spatial resolution and a low material budget. To handle the high interaction rates of LHC Run 3, the detector employs a digital readout system. This work focuses on studying the cluster topology of signals left by charged particles passing through the detector. By combining this information with the momentum of the particles, it is possible to infer the particle species. The performance of particle identification is further improved through the use of machine learning algorithms.
