Figure 8

Near- and away-side peak yields (first column), widths (second column), near-side peak $\beta$ parameter and baseline (third column) from fits to the D-meson and charged particle azimuthal-correlation function, from PYTHIA8 simulations obtained with different parton-level contributions. The predictions are obtained for multiplicity-integrated \pp collisions at $\s = 13$ \TeV, as a function of the D-meson $\pt$, for $\ptass > 0.3$ \GeVc, and compared with ALICE data.
