Abstract

This chapter is devoted to the description of the systematic uncertainties that were studied for each observable in Pb–Pb and p–Pb collisions. The various sources of uncertainty are listed in Table 6.1. In the first part of the chapter, the methods applied to evaluate the “data systematics” (yield extraction, correction for reflections, tracking/cut/PID efficiency and Monte Carlo \(p_\text {T}\) and multiplicity distributions) are presented. The description of the systematic uncertainty related to the B feed-down subtraction and to the scaling of the pp reference cross section needed to compute the nuclear modification factor are given in Sects. 6.7 and 6.8, respectively. In the last four sections the values of the uncertainties for each measured observable are summarized, in particular: Sect. 6.9 is devoted to the \(\text {D}^0\)\(v_2\) measurement, Sect. 6.10 to the azimuthal dependence of the \(R_\mathrm{AA}\), Sect. 6.11 to the minimum-bias measurements in p–Pb collisions (namely the \(p_\text {T}\)-differential cross section and \(R_\mathrm{pPb}\) and the \(p_\text {T}\)- and y-differential cross section), Sect. 6.12 to the multiplicity-dependent analysis carried out in p–Pb collisions (namely the \(Q_\mathrm{pPb}\) and the relative yields as a function of multiplicity).
