Description

Heavy quarks (charm and beauty) serve as useful probes for investigating the properties of the quark-gluon plasma (QGP) generated in ultrarelativistic heavy-ion collisions. The characterisation of the heavy-quark in-medium energy loss and of their diffusion process within the medium are, in particular, of great interest.

In this contribution, measurements of charm-hadron $R_{\mathrm{A}\mathrm{A}}$ and of prompt- and non-prompt D meson $v_2$ coefficient in Pb--Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=5.02$ TeV will be shown, along with comparisons to model predictions that incorporate various implementations of heavy-quark interaction and hadronisation with the QGP constituents. Angular correlations of heavy-flavour decay electrons with charged particles, and their modification in the presence of the QGP will be also presented. The latest findings from the LHC Pb--Pb Run 3 data will be featured, showcasing the performance of $v_2$ measurements for charm mesons and baryons.
