Photoproduction of quasi-bound ω mesons in nuclei

We propose the (γ,p) reaction as a means of producing possible quasi-bound states of ω mesons in nuclei. We use an effective Lagrangian, based on chiral SU(3) symmetry and vector meson dominance, in order to construct the ω-nuclear potential. The contribution of bound ω states is observable in the missing energy spectra of protons emitted in forward direction for several nuclei.
