Abstract
The phenomenological analysis of J/ψ and D meson production in Pb–Pb collisions at a center-of-mass energy of 2.76 TeV per nucleon pair is fulfilled in the framework of the two-component HYDJET++ model, which includes the thermal and nonthermal production mechanisms. A significant fraction of D-mesons is found to be in a kinetic equilibrium with the created matter, while J/ψ-mesons are characterized by earlier (as compared to light hadrons) freeze-out.
