We present results for the quenching, elliptic flow and azimuthal correlations of heavy-flavor 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 and a thermal parton
from the medium. The flow of the light quarks is shown to affect significantly the
and
of the final
mesons, leading to a better agreement with the experimental data. The approach allows also predictions for the angular correlation between heavy-flavor hadrons (or their decay electrons) and the charged particles produced in the fragmentation of the heavy-quark strings.
