The silicon vertex detector is a part of the NICA-MPD tracking system, designed for efficient detection of the short-lived products of nucleus–nucleus interactions. The paper presents the results of computer simulations of the identification capability of the MPD tracking system, when reconstructing the decays of D⁺ produced in central Au+Au collisions at ?S_NN “9 GeV. Both, the time-projection chamber and the vertex detector based on monolithic active pixel sensors were taken into consideration.
