[Clas_hadron] Talk at Hadron 2017 Conference

[Viktor Mokeev]

 Dear Ken,

 You have a nice and clear talk!

 Few comments and edits for your consideration:

slide # 2

Two-pion  electroproduction: N* structure--------------> Exclusive meson electroproduction: N*  Structure

You may ask Ralf for few slides on the electroproduction data off neutrons bound in deuterons
-----------------------------------------------------------

slide #3
More N* resonances predicted than observed.---------->

More N* resonances predicted not only in quark models but also from the recent LQCD studies than observed
-----------------------------------------------------------

slide #7

Evidence for 2 new “missing” resonances----------> Strong evidence for 2 new “missing” resonances

-------------------------------------------------------------

slide #21

 Are there evidences for N*--->f^0 N decays? If no, why you add diagram with N* in s-channel?

----------------------------------------------

slide #28

Meson-baryon terms contribute significantly. ------------->

-complex interplay between inner core of threee dressed quarks and external meson-baryon cloud
-successful description of Delta and N(1440)1/2+ electroexcitation amplitudes starting from the QCD Lagrangian
-capability to explore evolution of dressed quark mass was demonstrated

For better justification of the first bullet see the attached slides.

   Have a nice talk!

  Best Regards,
                      Victor

Dear Hadron Spectroscopy Working Group, 




I will be giving an invited talk at the Hadron 2017 Conference next week (Sept. 25-29). A draft of my talk is posted at:

Sorry for the short notice, as my talk is scheduled on Monday morning. Please send comments to: hicks at ohio.edu 




Best regards,
