[G12] Spectroscopy Working Group Presentation

[Reinhard Schumacher]

Hello Diane,
	Responding to Lei's comment, on Page 13 you probably want to say the 
intermediate state is the f1(1285), not the eta(1295).  That would be 
consistent with what Ryan Dickson is seeing in the g11 data.  The g11 
photoproduction results are much more consistent with f1 production via 
that diagram that eta.
