摘要：
ALICE measured the nuclear modification factor (R-AA) and elliptic flow (v(2)) of D mesons (D-0, D+, D*(+) and D-s(+)) in semi-central Ph-Ph collisions at root s(NN) = 5.02 TeV. The increased amount of data in semi-central Pb-Pb events obtained with the LHC Run 2 provides access to more precise measurements for the R-AA and the non-strange D-meson v(2) with respect to Run 1 results, as well as to the first measurement of the D-s-meson v(2) at LHC energies. The first application of the Event Shape Engineering technique in the analysis of the v(2) coefficient of D-0 and D+ mesons is also illustrated.
