Abstract

The paper describes the reconstruction algorithm for charged particle tracks formed at the primary interaction vertex for the designed SPD experiment at the NICA collider. The main components of the reconstruction program are the search for primary track segments in the vertex detector, estimation of their parameters, and track extrapolation in the track system of the SPD experiment. Track extrapolation takes into account the magnetic field and the effects of passing through matter, such as multiple scattering and energy loss of charged particles. Track parameters are evaluated using the Kalman filter. The developed program showed high efficiency of track reconstruction and is included in the SPD experiment software.
