Abstract
Improving the accuracy of reconstruction of the decay vertices of short-lived particles plays a fundamental role in the heavy-flavor sector of the MPD physics program. The MPD inner tracking system (ITS) based on a new generation of silicon detectors,—monolithic active pixel sensors (MAPS)—would certainly offer new possibilities within the scope of charm particle detection. A quality assessment of the MPD tracking system including ITS and time projection chamber (TPC), when reconstructing the decays of D‑mesons produced in central Au + Au collisions at \(\sqrt {{{s}_{{NN}}}} \) = 9 GeV has been performed in the course of computer simulations in the Mpdroot framework. The selection of D-meson signals in the invariant mass spectrum of their decay products was performed using a toolkit for multivariate data analysis.
