Distributions of zch || -differential yield of charm jets tagged with D0 mesons normalised by the number of D0 jets within each distribution in pp collisions at √s = 13 TeV in four jet-pT intervals 5 < pT,ch jet < 7 GeV/c, 7 < pT,ch jet < 10 GeV/c, 10 < pT,ch jet < 15 GeV/c, and 15 < pT,ch jet < 50 GeV/c 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.
