[Pwg] [EXTERNAL] Positrons and TPE at QCD Town Hall

[Jan C. Bernauer]

Hi all,

Certainly you should also mention TPEX.

Also, I would make clear that a measurement of the discrepancy (by 
comparing polarized to unpolarized) is not a measurement of TPE.  For 
that, you really need to compare positron to electron scattering.

Best,

Jan
