The CLAS Collaboration at Jefferson Lab conducted a photoproduction experiment on a proton target using a tagged photon beam with an energy range of 1.5-3.8 GeV during May-July 2004. With an integrated luminosity of about 75 pb−1, this experiment provides the largest data set for photon-proton reactions ever collected. The reaction γp→K+K+Ξ−(1320) has been investigated and the preliminary results of the cross section measurement of Ξ−(1320) for the photon energy range of 2.7-3.8 GeV have been obtained. In a search for excited cascade states, the reaction of γp→K+K+π−(Ξ0(1320)) has also been explored.
