Probability density distribution of $\Delta_{\pt}$ (left) and $\Delta_{z}$ (right) for \Dzero-meson tagged jets in \pp\ collisions at $\s=7$ TeV. Left: $\Delta_{\pt}$ is shown for $5< \ptchjetgen< 6$ \GeVc\ (circles), $8< \ptchjetgen< 10$ \GeVc\ (squares) and $20< \ptchjetgen< 30$ \GeVc\ (diamonds) Right: $\Delta_{z}$ is shown for $0.8< \zpargen< 1$ (diamonds), $0.6< \zpargen< 0.8$ (squares), $0.2< \zpargen< 0.4$ (circles); solid markers are used for $5< \ptchjetgen< 15$ \GeVc, while open markers represent $15< \ptchjetgen< 30$ \GeVc (the data set for $0.2< \zpargen< 0.4$ is omitted for the latter).
