Tentative agenda:
- Revision of the PAC46 proposal to resubmit it for PAC47
- GlueX Collaboration’s endorsement. There is an endorsement letter signed by key people of experimental groups of the GlueX Collaboration [1]
- Definition of GlueX Collaboration endorsement from bylaws
- Timeline for PAC47 approval within GlueX
- April 1: Proposal proponents request an internal review for endorsement
- April 8: Draft proposal submitted to internal review committee with charge from CB
- May 15: Internal review committee responds to charge, then CB and EG decide if proposal will be put up for a vote (at Collaboration Meeting)
- May 27: Initiate vote for proposal endorsement (2 weeks for vote)
- June 10: PAC47 proposal deadline
- For the April 8th deadline we plan to address the comments from the previous (PAC46) report:
- Effects of systematic uncertainties on our results
- Lack of awareness of competition in the international community, and impact this has on scheduling
- The proponents should describe the physics impact (for example, how will new baryon states test lattice QCD?), including effects of systematic errors on partial wave analyses.
- Demonstrate that systematic errors are under control, given the very small systematic errors expected, including energy resolution and acceptance at low -t.
- New calculations for KLP-->K+Xi0
- News for the flux monitor
- News for the Be-production target
- News for CPS
- News for the recent GlueX run with the Be-target
- Schedule for KLF meetings
The total cross section for KLp-->K+Xi0 and impact for Sigma(2030)7/2+ [2] and Sigma(1950)5/2-[3]. Differential cross section at W = 1940 MeV to compare 100 and 20 day run period [4]. Similar for pol measurements [5].
