摘要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) circle times O (3)](sym.) circle times SUC (3) quark model of baryon structure with only one same input parameter, the only strong coupling constant elm. Calculations for the cross sections, p-polarization of gamma + p -> K+ + Lambda reaction and the branching ratios for K- radiative capture of K- + p -> gamma + Y with Y = Lambda, Sigma(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.
