[Clas_hadron] Fwd: Abstract for MeNu2013

[Viktor Mokeev]

Hi Peng,

 Please find few suggestions on the abstract text

While
Quantum-Chromodynamics (QCD) is regarded as a mature theory
describing the interactions of quarks within hadrons, the excited states of
the nucleon present many challenges.--------->

While
Quantum-Chromodynamics (QCD) is regarded as a mature theory for pQCD regime, the strong interaction in non-perturbative regime remains most challenging part of the Standard Model we have to explore. Studies of nucleon resonances allow us to explore complexity of non-perturbative strong interaction through their manifestations in N*-states of different quantum numbers. 


 Recent Lattice-QCD calculations
have confirmed the long-standing predictions of effective quark models...----->

 The Lattice-QCD results on the studies of N*-spectrum 
are consistent with the long-standing predictions of effective quark models...

Your current wording looks excessively strong for me. Note, that LQCD computation of N* spectrum were carried out for pion mass around 400 MeV resulting in too heavy resonances and problems with the state order. It is questionable whether LQCD with
pion mass around 400 MeV is able to account for dynamical chiral symmetry breaking, which plays a key role in generation of N* spectrum. So, I would prefer more realistic statement on the LQCD results.


by partial wave analysis of many polarization observables.------------>
by analyses of unpolarized cross sections and many polarization observables combined.

Note that both PWA and reaction model analyses may be employed for extraction of N* parameters from your data.  

Please clarify explicitly which asymmetries you are going to produce. 


...and polarized neutrons.---->
...and polarized neutrons bound in deuteron (unless you are planning to get "free" neutron result. If so, explain how)

 Best Regards,
                            Victor

Peng, 
Abstract looks good. I would suggest to explicitly note I your abstract that you are looking for two CHARGED pions.

Dear Dave, 

I would like to give a talk about the "G14 Polarization Observables for 
Double Pion Photo-production" at MeNu2013 conference. I have sent it to 
Dennis and Bill for review. I also need to send it to the hadron 
spectroscopy group, but I am restricted to post in the mailing list 
right now. Could you please forward the abstract to the Hadron Group? 

Thank you, 
Peng
