Figure 2

Near-side (left panel) and away-side (right panel) peak yields (first row) and widths (third row) obtained from a fit to the azimuthal correlation function after the baseline subtraction. The measurements are compared with ALICE results obtained in pp collisions at $\sqrt{s}$ = 5.02 TeV  and 7 TeV , for 0.3 $<\ptass<$ 1 GeV/$c$, 1 $<\ptass<$ 2 GeV/$c$. Only near-side observables were computed in the $\sqrt{s}$ = 7 TeV analysis. The ratios to the $\sqrt{s} = 5.02$ TeV results are shown in the second and fourth rows for yields and widths, respectively.
