[Clas_hadron] APS meeting presentation

[mokeev at jlab.org]

Hi Sungkyun,

 Your results look very interesting for the exploration of pi^+pi^-p
photoproduction mechanisms in combined analysis of unpolarized cross
sections and polarization observables of this exclusive channel. This
analysis will allow us to improve our knowledge on N* spectrum and
photocouplings.

Few suggestions:


slide # 3

Replace you bullet as

Single and double pion exclusive channels are major contributors in N*
excitation region

(from you plots on slide #3 it is clear that single and double pion
channel cross sections are comparable).

slide #6

For description of the 3-body pi^+pi^-p final state your should have 5
kinematic variables BESIDE E_{gamma}. You have just four. One variable is
missing.

slide#12

What is the difference between quasi-free proton and bound nucleon? It is
unclear from slide.

slide #13

What does it mean the proton polarization in a case of proton Fermi motion?


Best Regards,
                      Victor
