[G12] Proton-Eta and Phi-Eta Plot

[Lei Guo]

Hi, Mukesh,

Do you have the predicted distributions for M(p_eta) using your PWA  
results?
If your data does contain the two N*'s, then your PWA predictions  
should not be able to describe the M(p_eta) spectra, and it will be  
another powerful evidence for the N* contributions. We could even get  
some phi/N* cross sections, which I don't believe have been measured  
by anyone.
