Figure 5

Nuclear modification factor $\RAA$ of prompt $\Ds$ mesons (left panel) and non-strange D mesons~ (right panel) in the 0--10\% centrality interval in Pb--Pb collisions at $\sqrtsNN=5.02~\TeV$ compared with theoretical calculations based on charm-quark transport in a hydrodynamically expanding QGP implementing strangeness enhancement and hadronisation of charm quarks via coalescence in addition to fragmentation in the vacuum~. The boxes represent the total systematic uncertainties. The colour bands represent the theoretical uncertainty when available.
