Modern detector technologies of D-mesons identification for investigation of superdense nuclear matter

In this work, new vertex detector for the precision registration of D mesons was proposed for MPD experiment at NICA collider. This conception includes three cylindrical inner layers of large area thin (40–50 [Formula: see text]m) silicon pixel sensors, bended around the collider beam pipe and located at a minimum distance from the interaction point of the beams. Also, detailed calculations of identification capability of this vertex detector, within the framework of the decays reconstruction of [Formula: see text] and D 0 mesons formed in central Au-Au collisions at the NICA collider energies, have been done. Using these estimates of D mesons reconstruction efficiency, the yields of such mesons in MPD experiment were obtained.
