Coupled-channel analysis of the omega-meson photoproduction in the resonance energy region — •Vitaly Shklyar, Horst Lenske, and Ulrich Mosel — Institut für Theoretische Physik I, Giessen Universität

Omega-meson photoproduction is studied to explore the nucleon resonance couplings to the final omega-nucleon system. The production amplitude is obtained within a coupled-channel unitary Lagrangian model which allows for the simultaneous analysis of pion- and photon-induced reactions. The resonance parameters are constrained by direct comparison with the available experimental data. The present study extends our previous results by including all available experimental data on the omega photoproduction off the proton and neutron.
