Exclusive analysis of the gamma(pol.) n ---> K+ Sigma- reaction at E(gamma) = 0.8-GeV to 2.3-GeV
Strangeness channels are important in the experimental search for missing resonances. A recent experiment performed at Jefferson Lab (CLAS gl3 run period) used a liquid deuterium target with linearly and circularly polarized tagged photon beams covering energies from threshold to 2.5 GeV. It provides high-quality data (about 52 billion triggers) with good kinematic coverage and several experimental observables available for each reaction channel. We have analyzed a few percent of these data to measure strangeness photoproduction on the neutron, in particular, the yn --> K+ Sigma- reaction. The exclusive analysis of this reaction along with a very preliminary measurement of the photon beam asymmetry is presented.
