Abstract

Photoproduction of the cascade resonances has been investigated in the reactions γp → K + K +(X) and γp → K + K + π −(X). The mass splitting of the ground state (Ξ⁻,Ξ⁰) doublet is measured to be 5.4 ± 1.8 MeV/c², consistent with existing measurements. The differential (total) cross sections for the Ξ⁻ have been determined for photon beam energies from 2.75 to 3.85 (4.75) GeV and are consistent with a production mechanism of Y∗→K+Ξ⁻ through a t-channel process. The reaction γp→K+K+π−[Ξ⁰] has also been investigated to search of excited cascade resonances. No significant signal of excited cascade states other than the Ξ⁻(1530) is observed. The cross-section results of the Ξ⁻(1530) have also been obtained for photon beam energies from 3.35 to 4.75 GeV.
