Kaon photoproduction off nucleons in the chiral quark model
- Physics Department, Carnegie-Mellon University, Pittsburgh, Pennsylvania 15213 (United States)
In this paper, we develop a general framework to study meson photoproduction off nucleons in the chiral quark model. The {ital s}- and {ital u}-channel resonance contributions are expressed in terms of the Chew-Goldberger-Low-Nambu (CGLN) amplitudes. The kaon-photoproduction processes, {gamma}{ital p}{r_arrow}{ital K}{sup +}{Lambda}, {gamma}{ital p}{r_arrow}{ital K}{sup +}{Sigma}{sup 0}, and {gamma}{ital p}{r_arrow}{ital K}{sup 0}{Sigma}{sup +}, are calculated. The initial results show that the quark model provides a much improved description of the reaction mechanism for kaon photoproduction off the nucleon with less parameters than the traditional phenomenological approaches.
