\pt-differential production cross sections of non-prompt \Dzero and \Lc hadrons in pp collisions at ${\s=13 \TeV}$ compared with predictions obtained with \fonll calculations  adopting \fbtoB and \fbtoLb fragmentation fractions measured in \ee collisions  and LHCb Collaboration  (left panel) and the \tamu model  (right panel) combined with \pythia  for the \HbtoHc decay kinematics.
