Evaluation of the tracking system efficiency in the CBM and NICA-MPD experimental setup
N.A. Prokofyev

This work is devoted to tracking system simulation for the following experimental setups: CBM (GSI, Darmstadt, Germany) and NICA-MPD (JINR, Dubna, Russian Federation). The main goal was to evaluate the track reconstruction efficiency in these currently developing setups.
Different realistic simulation models of the inner tracker for the CBM (Compressed Baryonic Matter) experiment were created and studied in detail. Based on the data obtained are the following results: 1) readout cables have a significant impact on the reconstruction parameters; 2) double increase of the sensor thickness 4 times downgrades the reconstruction efficiency for hyperons produced in Au+Au collision at 25A GeV.
   Realistic model of the Inner Tracking System and baseline hit producer were created for the NICA-MPD (Nuclotron-based Ion Collider fAcility – Multi-Purpose Detector) project.  Simulation results allowed us to calculate the detector occupancy and other tracking parameters. Signal overlap probability for each sensor in the ladder of microstrip detectors is uniform and does not exceed the value of 5%. This fact proves the correct choice of the ITS sector structure.
