【 摘 要 】

We present results for the quenching, elliptic flow and azimuthal correlations of heavy flavour particles in high-energy nucleus-nucleus collisions obtained through the POWLANG transport setup, developed in the past to study the propagation of heavy quarks in the Quark-Gluon Plasma and here extended to include a modeling of their hadronization in the presence of a medium. Hadronization is described as occurring via the fragmentation of strings with endpoints given by the heavy (anti-)quark Q(Q¯) and a thermal parton q¯(q) from the medium. The flow of the light quarks is shown to affect significantly the RAAand v2of the final D mesons, leading to a better agreement with the experimental data.
