[Clas12_deepana] [EXTERNAL] Abstract for APS

[Volker Burkert]

Dear Pierre, 
Could you clarify one aspect in the abstract.
 
You are talking about the photon polarization that you will show and compare to models. 
I am confused about this. 
You start with a polarized electron beam, and the interaction with the proton is therefore through 
a circularly polarized photon. But that is just a QED process and precisely calculable. 
When you refer to photon polarization, do you mean the time-like photon decaying to e+e-? 
If that is so, you may want to rephrase the corresponding sentence in the abstract.  
   
Otherwise it is a nice abstract. 

Best regards,
Volker
