[Clascomment] OPT-IN:EMC Effect and Correlated Nucleons: When One Plus One is not Two

[Reinhard Schumacher]

Hello Colleagues,

I have read your draft CLAS paper "EMC effect and correlated nucleons:  when 1 + 1 != 2" and have just a few comments.   This is another very nice paper on the topic of SRC that I think will get a lot of attention.   It is mostly well constructed and written well, but I have a few suggestions that you may consider to making it even better.

Figure 1:   This figure is not very informative in my view.   The message of the cartoonish film strip is not clear.   There must be a better way to illustrate the idea that the np_SRC configuration is not the same as "the sum of the parts".   If the point is that correlated quarks are "slower" than quarks in separate nucleons, maybe dream up a figure that includes arrows representing the speeds of the quarks being smaller in the case when the nucleons overlap.

Figure 2:   This is a very powerful figure:   it supports the results in a very impressive way.  However, the text in the legend is nearly impossible to read.   Consider getting rid of the big fat arrow between panels and increasing the size of the text underneath it.    Alternatively, stack the two panels so each half can be made bigger.

Line 181:  How nice it is to bury all the complications in "Supplemental material", your Ref 18.   The reference is not complete as given is it?  Where will this material be archived?  Can CLAS people see it now, and if not, why not?

Figure 3:  I seem to have missed where the vertical axis is defined.   What is being plotted here?   That is, what is dR^n_EMC/dx?  Please explain this better.

Ref 12:  is missing.

Ref 18: is missing.

Finally, who is lead author Schmookler?  Apparently he is a limited CLAS member. But is he an MIT student, or something else?   If he is a student, does he have a thesis to put on the CLAS thesis page?  (I happen to be the person who likes to keep that web page up to date.)

Best Regards,
Reinhard
