Abstract

The recent data taken by the CLAS Collaboration at the Thomas Jefferson National Accelerator Facility for the reaction of $γ p \to K^{+} K^{+} Ξ^{-}$ are reanalyzed within a relativistic meson-exchange model of hadronic interactions. The present model is an extension of the one developed in an earlier work by Nakayama, Oh, and Haberzettl [Phys. Rev. C 74, 035205 (2006)]. In particular, the role of the spin-5/2 and -7/2 hyperon resonances, which were not included in the previous model, is investigated in the present study. It is shown that the contribution of the $Σ (2030)$ hyperon having spin- $7 / 2$ and positive parity has a key role to bring the model predictions into a fair agreement with the measured data for the $K^{+} Ξ^{-}$ invariant mass distribution.
