Abstract
- A multi-step setup for heavy-flavour studies in high-energy nucleus–nucleus collisions is presented. The initial hard production of Q Q ¯ pairs is simulated with the POWHEG pQCD event generator, interfaced with the PYTHIA parton shower. In a nucleus–nucleus collision the propagation of the heavy quarks in the medium is described through the relativistic Langevin equation. The numerical results are compared to experimental data from the RHIC and the LHC. In particular we show the comparisons of the nuclear modification factor of D-mesons, non-prompt J / ψ 's and heavy-flavour electrons. Furthermore, first results on azimuthal correlations of heavy quark pair and open charm/beauty meson pairs are presented.
