Figure 4

The ratios of (anti)proton to charged-pion and (anti)deuteron to (anti)proton computed by PACIAE + DCPC model (the open symbols) as a function of \(p_{T}\) in pp collisions, as well as the most central (0–5%) and peripheral (40–60%) Pb–Pb collisions at \(\sqrt{s_{NN}}=2.76\,\hbox {TeV}\), respectively. Here, ALICE results (the solid markers) for comparison were take from Ref.2 in panel (c), and were computed with the data from Ref.2,3 in panel (d). The vertical lines (error bars) show the statistical uncertainty and the shaded areas represent the systematic uncertainty of the experimental results.
