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>
