Abstract

The results on the azimuthal anisotropy of D meson production in Pb–Pb collisions at \(\sqrt{s_\mathrm{NN}}=2.76\) TeV are presented in this chapter. The azimuthal anisotropy was quantified in terms of the elliptic flow \(v_2\) and of the nuclear modification factor \(R_\mathrm{AA}\), measured in the direction of the event plane and orthogonal to it. Section 7.1 is devoted to the \(v_2\) results: the \(\mathrm{D}^{0}\) elliptic flow is presented as a function of \(p_\mathrm{T}\) in the 30–50 % centrality class. \(v_2\) was also measured in the 0–10 % and 10–30 % centrality classes to investigate its dependence on the collision centrality. The average D meson elliptic flow is compared in this section with the charged-particle \(v_2\) measured with the event-plane method. The results of the \(\mathrm{D}^{0}\) \(R_\mathrm{AA}\) measured in the in-plane and in the out-of-plane regions, in the 30–50 % centrality class, are presented in Sect. 7.3. Section 7.4 is devoted to the comparison of the average D meson \(v_2\) in the 30–50 % centrality class, the average D meson nuclear modification factor in 0–20 % Pb–Pb collisions, and the \(\mathrm{D}^{0}\) meson \(R_\mathrm{AA}\) in-plane and out-of-plane to theoretical calculations.
