Measurements of away-side associated peak yields (top row) and widths (third row down) in \pp collisions at $\s = 5.02$~\TeV, compared to predictions by the PYTHIA, POWHEG+PYTHIA6, POWHEG LO+PYTHIA6, and HERWIG event generators with various configurations (see text for details). The ratios of yield (width) values with respect to the predictions by POWHEG+PYTHIA6 are shown in the second (fourth) row down. Results are presented as a function of the D-meson $\pt$, for $\ptass > 0.3$~\GeVc, $0.3 < \ptass < 1$~\GeVc, $1 < \ptass < 2$~\GeVc, and $2 < \ptass < 3$~\GeVc (from left to right). Statistical and systematic uncertainties are shown as vertical error bars and boxes, respectively.
