Abstract
This chapter introduces the experimental observables that were studied for this thesis. The two quantities that were used to investigate the azimuthal anisotropy of the \(\text {D}^{0}\) production in semi-peripheral Pb–Pb collisions, namely the elliptic flow \(v_2\) and the nuclear modification factor azimuthal dependence, are defined in Sect. 4.1. Section 4.2 is devoted to the definition of the observables that were measured to study the \(\text {D}^{0}\) production in minimum-bias p–Pb collisions: the \(p_\text {T}\)- and y-differential cross sections and the nuclear modification factor \(R_\mathrm{{pPb}}\). The observables used to investigate the dependence of the \(\text {D}^{0}\) production on event activity are also defined. The strategy to obtain the \(\text {D}^{0}\) proton–proton cross section at the proper energy, which is used to compute the nuclear modification factor both in Pb–Pb and p–Pb collisions, is described in the last part of the chapter (Sect. 4.3).

Prompt \(\text {D}^{0}\) are the mesons coming directly from the fragmentation of the c quarks. The \(\text {D}^{0}\) which results from beauty meson decays are defined as “feed-down \(\text {D}^{0}\)”.
