[Clas_hadron] Fwd: Re: [Halld-physics] DNP abstract

Tue Jun 25 18:29:31 EDT 2019

Hello all,

To bring the discussion here, this talk may be split into 2: 1 for 
CLAS12 and 1 for GlueX (depending on postdocs) or into 1 about 
exclusively CLAS12. Just to give an update about who is involved in the 
discussion/project/etc.

All the best,

Izzy
