[Clas_hadron] Cole talk at IX LASNPA

[Biplab Dey]

Hullo Phil,
Nice talk. A couple of comments:
1) Slide 15: I'm confused...aren't the t- and s-channels flipped? Also, as
a suggestion, I usually find the Wolf paper Fig. 11 to be a good
illustration for the spins:

2) Slide 16-17: are these distributions acceptance corrected? If not, that
should be mentioned.
3) Slide 18: probably a better choice of colors can be taken than light
green, which is very hard to read from afar?
Btw, people usually associate the GJ frame as the ``Phi rest frame'',
because you actually need that boost, which is not the case for the Hel.
frame, for which you can just be in the CM frame and look at the helicity
transfer.
4) Slide 28: I'm kind of skeptical about these conclusions. That E_gamma
\sim 2 GeV is a problematic region due to the Phi-Lambda1520 overlap. I'd
probably be cautious before making general statements about the
non-resonant mechanisms, while being around E_gamma = 2 GeV.

Lastly, I didn't see any comparisons between these CLAS and the LEPS-2010
Chang results. Those data might be just at fwd-angles, but they are very
good actually.

Cheers,
Biplab
