At the Joint Institute for Nuclear Research (JINR) in Dubna, a complex of accelerators called NICA (Nuclotron-based Ion Collider fAŃility) is being built. One of its parts is the Multi-Purpose Detector (MPD), which is currently being assembled. The MPD experiment will study the phase diagram of QCD matter, including the properties of the phase transition and the location of the critical point, analyzing heavy-ion collisions in the energy range 4-11 AGeV. During the course of Ph.D. studies, the simulations of those collisions will be prepared and analyzed using the MPDRoot environment. Observables such as monoparticle and biparticle inclusive momentum spectra of identified particles, correlation functions, electromagnetic signatures, and production of charm particles will be studied. Data obtained during the simulations will be analyzed. The second part includes the calibration of the MPD’s subdetectors, namely Time of Flight, Time Projection Chamber, and other, using cosmic rays and storing the calibration data in the Equipment Database (EqDb). The EqDb is still under development. The first year of the Ph.D. was conducted at JINR, unfortunately, due to COVID-19 restrictions, work was mostly done in a remote mode.
