(Left) Charmed baryon-to-meson $\Lc/\Dzero$, $\rm \Sigma_{c}^{0,++}/\Dzero$, and $\XicPlusZero{}/\Dzero$ ratios in pp collisions at $\sqrt{s}$ = 13 TeV, in comparison with PYTHIA 8. (Right) Charm and beauty production cross sections per unit of rapidity at midrapidity as a function of the collision energy . STAR and PHENIX measurements in pp collisions at $\sqrt{s}=$ 200 GeV are slightly displaced along the horizontal direction for visibility. Comparison to the FONLL model calculations  and NNLO calcuations  are reported.
