Based on the low energy QCD Lagrangian theory and the crossing symmetry relation, strange meson photoproduction and its associated radiative capture on the proton are investigated in the [SUSF(6) (×) O(3)],ym. (×) SUC(3)quark model of baryon structure with only one same input parameter, the only strong coupling constant αM. Calculations for the cross sections, p-polarization of γ + p → K+ + Λ reaction and the branching ratios for K- radiative capture of K- + p →γ+ Y with Y = Λ, ∑0 are performed. Good agreements to data are obtained and the results show that,compared to traditional phenomenological models, the low energy QCD Lagrangian theory provides a successful, unified description of the strange meson photo-production and its associated radiative capture.
