STUDY OF K-MESON PHOTOPRODUCTION AND ASSO CIATED RADIATIVE-CAPTURE PROCESS

We analyse K-meson photoproduction off proton and its associated radia tive capture process in Low Energy QCD Lagrangian. The two processes a re related to each other by the Crossing Symmetry. In the framework of chiral quark model, we give a unified description of the two processe s. Our theoretical prediction for branching ratio in radiative capture process is in good agreement with the experimental data.
