Hi All,

Sorry Silvia for the misunderstanding, I'm on holidays the week of the collaboration meeting so I won't be able to give this talk. I've attached slides showing improvements for J/psi produced on the bound proton and J/psi produced on the bound neutron. For whoever will give the talk, please feel free to take the plots you want from them and email any questions you have on the slides.

Unfortunately, we had some power outages due to flooding in our offices in Glasgow so I was only able to transfer over roughly 60% of spring 2019. On these 60% of spring2019 we see an improvement of:

  *   ~80% for J/psi produced on the proton ( ep_bound -> (e') e+ e- p ).
  *   ~50% for J/psi produced on the neutron ( en_bound -> (e') e+ e- n ).

Thanks,
Richard

Subject: [Clas12_rgb] Pass2 vs Pass1 talk at CLAS Meeting

Dear all,
next week at the CLAS meeting RGB will have a 15-minute slot to present
"Pass2: First look at RG-B data". My understand is that Richard is
available to give this talk (Richard, please correct me if I am wrong). It
would be great if this talk could provide an overview on the impact of
pass2 on all ongoing RGB analyses. Provided that Richard will be the
speaker, could all RGB analyzers please provide him with one slide
summarizing the impact of pass2 on their analyses? It can be focused on
the overall increase of the yields, and/or resolutions, improved PID, etc.
Thanks a lot and best regards,
Silvia
