Role of high-spin hyperon resonances in the reaction of $\gamma p\to K^{+}{K}^{+}{\Xi }^{-}$

Abstract

The recent data taken by the CLAS Collaboration at the Thomas Jefferson National Accelerator Facility for the reaction of $\gamma p\to K^{+}{K}^{+}{\Xi }^{-}$ 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 $\Sigma (2030)$ 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 $K^{+}{\Xi }^{-}$ invariant mass distribution.
