摘要：
One-loop corrections due to the intermediate piN and rhoN states are studied in omega photoproduction near threshold. Our results show that the coupled-channel effects should be taken into account in extracting reliable nucleon resonance parameters from the forthcoming vector meson photoproduction data in the resonance region.
