摘要：
The phenomenological analysis of various characteristics of J/psi and D meson production in PbPb collisions at the center-of-mass energy 2.76 TeV per nucleon pair is presented. The data on momentum spectra and elliptic flow are reproduced by two-component model HYDJET++ including thermal and non-thermal charm production mechanisms. The significant part of D-mesons is found to be in a kinetic equilibrium with the created medium, while J/psi-mesons are characterized by earlier (as compared to light hadrons) freeze-out.
