[Clas_hadron] DNP abstract

[Isabella Illari]

Hi Everyone,

Due to some discussion/conversation with Justin, Volker and Igor this is 
the updated abstract for the upcoming DNP meeting, appended to the 
bottom. Comments and suggestions are welcome.

All the best,

Photoproduction of the Omega- in JLab's Hall B CLAS12

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 experiments require an 11 
GeV beam and a liquid hydrogen target. 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.

This work was performed with support from US DOE DE-SC001658, The George 
Washington University, and Thomas Jefferson National Accelerator Facility.
