| Abstract | An unified approach to the pseudo scalar meson (π, η, and K) photoproduction off nucleons are presented. It begins with the low energy QCD Lagrangian, and the resonances in the sand uchannels are treated in the framework of the quark model. The duality hypothesis is imposed to limit the number of the t-channel exchanges. The CGLN amplitudes for each reaction are evaluated, which include both proton and neutron targets. The important role by the S-wave resonances in the second resonance region is discussed, it is particularly important for the K, η and η′ photoproductions.
