Abstract
Based on low energy QCD Lagrangian, and using wave function of baryon in [SuSF(6)⊗ 0(3)]sym.⊗ Suc(3) quark model, strange meson photoproduction off the proton is studied. Calculations of cross sections and p-polarization for γ + p → K + + Λ reaction are performed. The theoretical results show that, compared to traditional phenomenological models, the low energy QCD Lagrangian provides a successful description of the reaction process with only one free parameter, strongly coupling constant αm.
