[Clascomment] OPT-IN: Measurement of the nuclear multiplicity ratio for K0s hadronization at CLAS

[Mikhail Osipenko]

Dear Authors of K0 paper,

I have few comments on the presented paper:

1) abstract: "fractional virtual photon energy z" does not make sense to me, it's more like K0 energy in terms of the virtual photon energy fraction;

2) abstract: "transverse momentum broadened in the nucleus for large pt2" - probably misspelling, if you are differential in pt2 how can you definde "transverse momentum broadening" (I guess it needs some kind of integration in pt2)?

3) page 2: pt2 defined three times, in abstract, in paragraph 2, in paragraph 3, where the last definition is most complete one. Move it in abstract and remove others.

4) page 2, last paragraph: "In particular, several hadron species..." - unlikely you do want to discuss this presenting the results for only one hadron specie.

5) Fig.1 and discussion of Fig.1 in the text above it: personally I think it is not fair to present HERMES data in CLAS paper and moreover begin the paper with them (are we some sort of HERMES colony?). At most you can compare CLAS data with HERMES somewhere at the end of the article.

6) page 5 first paragraph: add some reference to justify cut in y (I believe it has never been demonstrated that RC increase at high y in SIDIS).

7) page 6: what do you mean under "radiative effects were too small to measure with present statistics"?

Best Regards,
               Mikhail.
