Thermal and non-thermal charmed meson production in heavy ions collisions at the LHC

Abstract

The phenomenological analysis of the LHC data on transverse momentum spectrum and elliptic flow of $J/\psi$ and D mesons in PbPb collisions at center-of-mass energy 2.76 TeV per nucleon pair is presented. The charmed meson production pattern in PbPb collisions may be reproduced by two-component model HYDJET++ including thermal and non-thermal components. The significant part of D-mesons is found to be in a kinetic equilibrium with the created medium, while $J/\psi$-mesons are not.
