• Abstract: We report measurements of the production of prompt D0 , D+, D∗+ and D+ s mesons in Pb–Pb collisions at the centre-of-mass energy per nucleon-nucleon pair √ sNN = 5.02 TeV, in the centrality classes 0–10%, 30–50% and 60–80%. The D-meson production yields are measured at mid-rapidity (|y| < 0.5) as a function of transverse momentum (pT). The pT intervals covered in central collisions are: 1 < pT < 50 GeV/c for D0 , 2 < pT < 50 GeV/c for D+, 3 < pT < 50 GeV/c for D∗+, and 4 < pT < 16 GeV/c for D+ s mesons. The nuclear modification factors (RAA) for non-strange D mesons (D0 , D+, D∗+) show minimum values of about 0.2 for pT = 6–10 GeV/c in the most central collisions and are compatible within uncertainties with those measured at √ sNN = 2.76 TeV. For D+ s mesons, the values of RAA are larger than those of non-strange D mesons, but compatible within uncertainties. In central collisions the average RAA of non-strange D mesons is compatible with that of charged particles for pT > 8 GeV/c, while it is larger at lower pT. The nuclear modification factors for strange and non-strange D mesons are also compared to theoretical models with different implementations of in-medium energy loss.
