D-meson nuclear modification factor and elliptic flow measurements in Pb–Pb collisions at \(\sqrt {s_{NN}}\) = 5.02TeV with ALICE at the LHC

Abstract

ALICE measured the nuclear modification factor \(R_{AA}\) and elliptic flow \(\nu_{2}\) of D mesons \(D^{0}\). \(D^{+}\). \(D^{⁎+}\) and \(D^{s+}\) in semi-central Pb–Pb collisions at \(\sqrt{s_{NN}} =5.02\) 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 \(\nu_{2}\) with respect to Run 1 results, as well as to the first measurement of the \(D_{s}\) -meson \(\nu_{2}\) at LHC energies. The first application of the Event Shape Engineering technique in the analysis of the \(\nu_{2}\) coefficient of \(D^{0}\) and \(D^{+}\) mesons is also illustrated.
