I think we need to be careful about simultaneous analyses of GlueX and data from another hall.We discussed these issues at the last collaboration meeting and the
<div class="">CB is working to provide some guidance. </div>

Photoproduction of the Omega- in JLab's Hall B CLAS12 and Hall D GlueX<br class="">

The photoproduction of the very strange hyperon, the Omega-, cross-section is unknown. The dynamics of the Omega photoproduction is unclear – there are no strange quarks in the initial case while three quarks are in the final state. There are theoretical predictions
for the Omega- hyperon photo- and electroproduction that varies from 1 to 300 pb, but there is only an upper limit of the cross section (σt < 17 nb at 20 GeV) reported by SLAC. In order to measure the cross section for γp → Ω−K+K+K0 and to study the reaction
mechanism for the Ω− in photoproduction we will analyze data from two of the experimental halls at Thomas Jefferson National Accelerator Facility. The CLAS12 physics program studies baryon spectroscopy with quasi-real photoproduction in a large variety of
final states, and Run Group A (RG-A) experiments require an 11 GeV beam and a liquid hydrogen target. The GlueX (Phase I) physics program studies experiments with a broad-band photon beam produced by ~12 GeV electrons. Thus, we are aiming to develop a better
understanding of the mechanism of "Very Strange" hyperon photoproduction, and to obtain accurate measurements of a cross section like the Omega- using data from CLAS12 and GlueX.<br class="">
