Abstract
The production of charm-hadrons at midrapidity in pp collisions at $\sqrt{s}$ = 5.02 and 13 TeV was recently measured by the ALICE Collaboration. The results show that the baryon-to-meson yield ratios are significantly higher than those measured in $\rm e^{+}e^{-}$ collisions for different charm-baryon species. These observations suggest that the charm fragmentation fractions are not universal and that the baryon-to-meson ratio depends on the collision systems. The results are compared to the predictions from Monte Carlo event generators and theoretical calculations.

Strengths
Weaknesses
The comparison to e+e- and ep is in terms of the yields, not the ratios, where D0 production decreases and Lambda increases... but this isn't highlighted in the text, and doesn't seem as general a conclusion as given in the abstract. Any clarification that can be added, to give a more coherent picture?
Report
Requested changes
-
Match abstract/conclusions to the three results shown.
-
Explain the combination of baryon/D0 ratios and frag function changes in a coherent picture, i.e. how general is the statement that baryon/D0 are generally higher than in e+e- and ep machines?
