Top left: ratio between the $\pt$-differential cross sections at midrapidity ($|y|<0.5$) of prompt $\Lambda_{\rm c}^+$ baryons and $\Dzero$ mesons in pp collisions at $\s=5.02$ TeV , 7 TeV  and $13$ TeV  The measurement of $\Lambda_{\rm c}^+/\Dzero$ ratio in \pp collisions at $\s=13$ TeV for $\pt>1$ GeV$/c$ uses the $\Lambda_{\rm c}^+$-baryon cross section published in Ref.  Bottom left: ratio between the $\pt$-differential cross sections at midrapidity ($|y|<0.5$) of prompt $\Lambda_{\rm c}^+$ baryons and $\Dzero$ mesons in pp collisions at $\s=13$ TeV compared with the predictions from PYTHIA Monash tune , PYTHIA CR-BLC Mode 0, 2 and 3 , SHM+RQM , Catania , QCM , and POWLANG  models in pp collisions at $\s=13$ TeV Top right: $\pt$-differential $\Xi_{\rm c}^+/\Dzero$ ratio in pp collisions at $\s=13$ TeV and $\Xi_{\rm c}^0/\Dzero$ ratio in pp collisions at $\s=5.02$ TeV  and $\s=13$ TeV . The $\Xi_{\rm c}^+/\Dzero$ ratio in pp collisions at $\s=13$ TeV for $\pt>4$ GeV$/c$ uses the $\Xi_{\rm c}^+$ published in Ref. . Statistical (systematic) uncertainties are reported as vertical bars (open boxes). The shaded boxes show the BR uncertainty Bottom right: $\pt$-differential $\Xi_{\rm c}^0/\Dzero$ and $\Xi_{\rm c}^+/\Dzero$ ratio in pp collisions at $\s=13$ TeV compared with the predictions from the models reported above.
