Abstract
As part of a broader study of kaon photoproduction on deuterium, the \gamma n \to K^{+} \Sigma^{-} 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 \to K^{+} \Sigma^{-} channel was identified by detecting the positive kaon in coincidence with both decay products of the \Sigma^- hyperon, \pi^- 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.
