[Hybrid baryons] Fwd: Fwd: Technical Advisory Committee Reports

[santopin]

Dear all,
I agree in each point with Viktor.
regarding point 3 probably Joe is meaning situations that  can  give 
origin to  poles even if they come from dynamically generated 
resonances,anyway there is leterature on that.
Cheers,Elena
