[Clascomment] OPT-IN:Suppression of neutral pion production in deep-inelastic scattering off nuclei with the CLAS detector

[Sebastian Kuhn]

Quick comments:
1) In the abstract, it says "We found that the neutral pion multiplicity ratio is maximally suppressed for the leading hadrons (energy transfer z → 1), varying from 25% on carbon up to 75% in lead." This could be misinterpreted as if the MULTIPLICITY ratio varies from 25% in carbon to 75% in lead, when I think you want to say that the SUPPRESSION varies like that.
2) Just a matter of taste, but I don't think it helps if we try to related everything to the "gravitational interactions" (energy of course also interacts gravitationally). I would suggest leaving out the first sentences in the intro, up to "Hadron formation is..." 
3) Fig. 2 caption doesn't seem to agree with what I see ("bottom horizontal ν axis")
