Today, the studies of the formation of hadrons containing heavy quarks are of particular interest for high-energy physics. At the energies of colliding nuclei of the NICA collider, one can study the yields of strange and charmed particles, as well as clusters of dense nuclear matter, and at fragmentation of such clusters the increasing of the heavy flavor particles yield could be observed. Therefore, the concept of a vertex detector based on silicon pixel detectors was developed for the efficient registration of short-lived particles in the MPD (Multi-Purpose Detector) experiment at the NICA collider, and for this vertex detector the main characteristics were obtained.
