Distributions of \zch-differential yield of charm jets tagged with \Dzero mesons normalised by the number of \Dzero jets within each distribution in \pp collisions at \thirteen in four jet-\pt intervals ${5<\ptchjet<7~\GeVc}$, ${7<\ptchjet<10~\GeVc}$, ${10<\ptchjet<15~\GeVc}$, and ${15<\ptchjet<50~\GeVc}$ from left to right, respectively. Top, middle, and bottom rows represent jets with $R=0.2$, $0.4$, and $0.6$, respectively. They are compared to PYTHIA~8 HardQCD Monash~2013 (dash-dotted lines), PYTHIA~8 SoftQCD Mode 2 (dashed lines), and POWHEG hvq + PYTHIA~8 (open circles) predictions. The shaded bands indicate the systematic uncertainty on the distributions Bottom panels present ratios of MC predictions to the data.
