[Clascomment] OPT-IN: phi-meson photoproduction on Hydrogen in the neutral decay mode

[Hicks, Kenneth]

Dear Jean-Marc,

Perhaps I can respond to your last comment.  The plan is to publish a paper in the future with the combined analysis of both neutral and charged decay channels.  The current papers are reporting just the data, but the combined paper will likely focus more on the physics that can be extracted from the comparison.  Please wait for that paper for more details.

Best regards,
Ken

Subject: [Clascomment] OPT-IN: phi-meson photoproduction on Hydrogen in the neutral decay mode

Dear Lead Authors,

In Figure 13, the slope parameter is certainly meant to be the slope parameter of the diffractive amplitude and not the slope parameter of the differential cross section, which according to previous experiments ranges around 6 GeV^2 (instead of 3).

In order to prevent confusion for the reader, I strongly suggest to:

1- Plot the slope parameter of the cross section, as it is usually done;

2- Define the meaning of "beta", even if you decide to stick to the present format of figure 13.

In the comparison with previous data, I do not understand why you do not include the latest CLAS charged decay mode results (CMU analysis) which are in the final stage of the review by the collaboration. Both analysis use the same data set and I guess that the author list will be quite similar. Also both papers will end up as a CLAS collaboration publication!!

All the best,

JM
