description: This work is devoted to studying the processes of simulation and reconstruction of tracks in the Spectrometer Straw Tracker (SST) of the future SHiP experiment (CERN) for search of new superweakly interacting particles that could explain the problem of the Dark Matter of the Universe. During the work on optimization of the Spectrometer Straw Tracker (SST) for simulation and reconstruction of tracks, geometric defects were identified in the FairSHiP package of the SHiP experiment software, and a solution was also proposed to eliminate them. The work was carried out on the basis of the Higher Engineering Physics School of the Peter the Great St. Petersburg Polytechnic University with the help of auxiliary data from the B. P. Konstantinov Petersburg Institute of Nuclear Physics of the NRC Kurchatov Institute. In this work, the processes of simulation and reconstruction of tracks were studied for the central track detector (SST) of the future SHiP experiment to search for new superweakly interacting particles. During the work on optimization of the central track detector (SST) for simulation and reconstruction of tracks, geometric defects were identified in the FairSHiP software of the SHiP experiment, and a solution was also proposed to eliminate them.
