[Clas_hadron] [EXTERNAL] Slides for EUNPC

[Valery Kubarovsky]

Igor,
In the recent presentations Gluex uses the form factor parametrization
[cid:66c49a6c-ac7f-43c9-acde-bc5fa61da065]
suggested in the paper of L. Frankfurt and M. Strickman, Eq. 3.

Hi Richard,

I have 2 comments for your slides for your consideration...

1) For pg 2: I do not think that this ref [ [3] L. Frankfurt, M. Strikman, Phys. Rev. D. 66, 031502 (2002).] makes any sense for GlueX data

2) Using GlueX threshold data, we determine J/psi-p scattering length (attached papers)

Cheers, Igor
