Abstract

D mesons and the Λc baryon are currently considered as one of the most perspective probes for search of quark deconfinement during transition of matter from a state of hadron gas to quark-gluon plasma. The tracking system of the MPD experiment at NICA collider will include the vertex silicon detector MPD-ITS designed for the efficient registration of these short-lived products of nuclear-nuclear interactions, to be built using Monolithic Active Pixel Sensors based on the MICA chip that is being developed in the framework of a specialized consortium that was formed as a result of the long-lasting collaboration between JINR and Chinese institutions led by the Central China Normal University (Wuhan). The second prototype of such a chip is expected to be received at JINR by October 2025. The present status of the MPD-ITS project is reported here.
