[G14_run] From Dao Ho: DNP presentation

[Volker Crede]

Dear Dao,

I noticed that you listed the E asymmetry for pi+pi- in your outline. On Slide 7, all y-axes are labeled E* Asymmetry but this cannot be correct. The E observable is the helicity difference and is a double-polarization observable. In the top right figure, you are comparing with Sungkyun Park's (g9a) and (most likely) with Steffen Strauch's g1c results. However, the latter had no target polarization. I am sure you mean the beam-helicity asymmetry which requires a circularly-polarized beam and an unpolarized target. 

Does the bottom row then show the beam-helicity asymmetries for the neutron or really the E observable?

Best wishes,

       Volker Crede
