Tentative Agenda

  1. Announcements
  2. Action Items
    1. Feedback from the Collaboration Review (Barry and Joerg)
    2. From Matt Shepherd
      • I intend to ask the CB to consider proposing a bylaw under D.3 "Access to Data" that explicitly states something along the lines that members of the theory community in collaboration with members of GlueX, may have access to data or preliminary results as needed to facilitate theory/experiment collaboration. I think that GlueX has a culture that such collaboration is encouraged, but it may be beneficial to state it explicitly. Some of our theory colleagues are used to working with collaborations that have rules forbidding such direct access to data.
      • (The bylaws already provide a provision for theory/non-member authorship.)
  3. Theory update
  4. Experiment update
    1. AmpTool Fits (Elton)
    2. More information at GlueX-doc-4421
  5. Updates to collaboration draft
    1. Backgrounds to be simulated
      • Background hits
      • BGGEN (PYTHIA)
      • eta production
    2. Experiment optimization
      • Target position (Beni)
      • Generate angular distributions for some other targets to compare to Pb
    3. Significance of experiment
      • The expected uncertainties of the extracted gg->pi0pi0 cross section (Fig. 24 of proposal) need to be verified and studied more carefully
    4. Analysis of PRIMEX data
  6. Other business
  7. Next meeting
