Description
The production of the excited states of the $\Xi^{-}$ hyperon from proton-kaon collision, $p + K^- \to \Xi^{*-} + K^+$, with the s- and u-channel processes has been studied. We employed the effective Lagrangian method to describe the production of $\Xi^{*-}$ and utilized the Regge model for the u-channel process. To determine the couplings and the form factors for $\Xi^{*-}$, we also carry out the quark model calculation by using the baryon wave functions of the constituent quarks with the quark-diquark description. As a result, we predicted the production rates of $\Xi^{-}(1320)$, $\Xi^{*-}(1530)$, and some excited states of $l = 1$. The relation between the production rates of the final state $\Xi^{*-}$ and the baryon structures of the $\Xi^{*-}$ and the intermediate states such as $\Lambda$, $\Sigma^0$, and $\Sigma^{*0}$ are discussed.
