Sigma{sup -} Photoproduction on the Neutron: Results from CLAS

Conference ·
OSTI ID:828511
As part of a broader study of kaon photoproduction on deuterium, the {gamma}n {yields} K{sup +} {Sigma}{sup -} channel was investigated. The data were acquired at Jefferson Lab using the CLAS detector and the Photon-Tagging Facility installed in Hall B. The photon energy range covered was from 0.50 to 2.95 GeV. For the present analysis, the {gamma}n {yields} K{sup +} {Sigma}{sup -} channel was identified by detecting the positive kaon in coincidence with both decay products of the {Sigma}{sup -} hyperon, {pi}{sup -} and n. Preliminary differential cross-sections are shown as a function of the invariant energy W and the kaon polar angle in the center of mass system.
