[Clas_hadron] Draft abstract for DNP2014

[Viktor Mokeev]

 Hi Tsuneo,

 Please find few suggestions:

Recent Lattice QCD calculations have confirmed--->
Recent Lattice QCD calculations have supported

So far, the LQCD results you mentioned were obtained with pion mass ~400 MeV which is still far from physical limit. 

 Furthermore, while I = 3/2 ∆ amplitudes can be determined from proton targets alone, descriptions of I = 1/2 N* production necessarily require neutron reaction data---->

Furthermore, for evaluation of isoscalar and isovector contributions to photocouplings of 1/2-isospin resonances, photocouplings both off protons and neutrons are needed.

 My point is: transition amplitudes (photocouplings) off protons are fully determined by the off proton photoproduction data both for N*-states of 1/2 and 3/2 isospins. If you want to get isoscalar and isovector components for N* states of 1/2 isospin, you do need the data off neutrons, while for Delta-resonances this problem is irrelevant, since we have only the contribution from isovector component.

 Best Regards,
                   Victor

Dear,

 I am attaching my draft abstract for DNP2014 in Hawaii and also you can find the pdf file
at "/u/site/www/html/Hall-B/secure/g14/Tsuneo/APS2014/abst.pdf".  
Your comments and suggestions are appreciated.

 I would like to mention that I already passed the draft to g14 email lists and got some 
comments.

   Regards, Tsuneo Kageya.
