Attended:

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]

- 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


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].


Sigma(1920)5/2- new

100d M = 1.923+-0.010+-10 GeV G = 0.321+-0.010+-10 GeV

20d    M = 1.977+-0.021+-25 GeV      G = 0.327+-0.025+-25 GeV  

PDG2018 M = 1.775+-0.005 GeV G = 0.120+-0.015 GeV

LQCD M = 1.212 GeV

           M = 1.487 GeV 
           M = 1.590 GeV
           M = 1.663 GeV


Sigma(2030)7/2+ ****

100d M = 1.930+-0.020+-0.030 GeV G = 0.400+-0.040 GeV

 20d   M = 1.981+-0.030+-0.030 GeV   G = 0.350+-0.080 GeV  

PDG2018 M = 2.030+-0.008 GeV G = 0.180+-0.025 GeV

LQCD M = 1.606 GeV

           M = 1.620 GeV 
           M = 1.670 GeV
           M = 1.678 GeV
