Study of track reconstruction at the LHCb experiment

The main aim of LHCb detector is to investigate decays of so-called B-particles, which are particles that contain b-quarks, and that clarifies more insightfully the phenomenon of matter-antimatter asymmetries. Using the LHCb Simulation Software, it has been made possible to generate and reconstruct displaced vertex types. July 2022 marks the beginning of RUN 3, which the detector underwent several changes during the shutdown in order to be ready for. The expected delivered instantaneous luminosity is L=2×1033cm2s-1. This report focuses on the study of particle tracks inside the detector, focusing mainly on the downstream tracks.
