Electro- and photoproduction of ω (783) mesons using CLAS at Jefferson Lab

Electro- and photoproduction of {omega}(783) from a proton target have been measured in the CLAS detector at the Thomas Jefferson National Accelerator Facility in Newport News, VA. The photoproduction data were taken over a photon energy range from 0.5 to 2.3 GeV, while the electroproduction data was obtained over a W range of 1.8--2.5 GeV/c{sup 2}. Preliminary acceptance-corrected center-of-mass angular distributions have been examined for both data sets.

Strange-particle physics at Jefferson Lab

The Continuous Electron Beam Accelerator Facility (CEBAF) at the Thomas Jefferson National Accelerator Facility is devoted to the investigation of the electromagnetic structure of mesons, nucleons, and nuclei using high duty-cycle electron and photon beams in the energy range up to 4 GeV. The basic features and the status of the accelerator and the experimental instrumentation are presented. The program to study strange particle physics is discussed, and some specific examples are given.
