Sumario: | The CMS experiment relies on an all-silicon Tracker for the reconstruction of charged particles in the hostile radiation environment of proton collisions at the LHC at CERN. Even if the core of the tracking software has not changed in years, several important improvements have been developed recently to increase the reconstruction efficiency of charged hadrons, reduce the rate of fake tracks and refine the overall quality of the reconstructed trajectories. Despite the higher level of complexity, the tracking software is much faster than before. An outline of the recent changes to the tracking software is given and current performance is described according to the most recent studies based on Monte Carlo simulations. |
