Photoproduction of Xi off nucleons

Abstract

The photoproduction reaction $\gamma N\to KK\Xi$ is investigated based on a relativistic meson-exchange model of hadronic interactions. The production amplitude is calculated in the tree-level approximation from relevant effective Lagrangians, whose (coupling constant) parameters are mostly fixed from the empirical data and/or quark models together with SU(3) symmetry considerations. Gauge invariance of the resulting amplitude is maintained by introducing the contact currents by extending the gauge-invariant approach of Haberzettl for one-meson photoproduction to two-meson photoproduction. The role of the intermediate low-lying hyperons and of the intermediate higher-mass hyperon resonances are analyzed in detail. In particular, the basic features of the production of ${\Xi }^{-}(1318)$ in $\gamma p\to K^{+}{K}^{+}{\Xi }^{-}$ and their possible manifestations in the forthcoming experimental data are discussed.
