Abstract (data abstract)
CERN-LHC. The azimuthal anisotropy coefficient $v_2$ of prompt $D^0$, $D^+$, $D^{*+}$ and $D_s^+$ mesons was measured in mid-central (30-50% centrality class) Pb-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}}$ = 5.02 TeV, with the ALICE detector at the LHC. The D mesons were reconstructed via their hadronic decays at mid-rapidity, |$y$|<0.8, in the transverse momentum interval 1<$p_{\rm T}$<24 GeV/$c$. The measured D-meson $v_2$ has similar values as that of charged pions. The $D_s^+$ $v_2$, measured for the first time, is found to be compatible with that of non-strange D mesons. The measurements are compared with theoretical calculations of charm-quark transport in a hydrodynamically expanding medium and have the potential to constrain medium parameters.
