A new model for photoproduction of KΛ, i.e. γ + p → K+ Λ and γ + n → K 0Λ has been constructed by using the Feynman diagrammatic approach. By using this approach, we have calculated the scattering amplitude analytically. In addition, we have also included a number of very-high-spin nucleon resonances, i.e. those with spins 11/2 and 13/2, which are listed by the Particle Data Group (PDG). The unknown parameters in the model, i.e., the hadronic coupling constants, were extracted by fitting the calculated observables to nearly 9000 experimental data points. The result of the model calculations is compared with those of previous investigations and experimental data. From the comparison we may conclude that the constructed model can nicely reproduce the experimental data.
