| dc.description | The $ω$-meson photoproduction, $γ+p\to p+ω$, is studied in the framework of a model, containing $π$-meson exchange in t-channel and nucleon-exchange in s- and u-channels. Considering both $ωNN$-coupling constants in the region of time-like meson four momenta as the free parameters, we find different sets of solutions for these constants from the existing data on the t-dependence of the differential cross sections, $dσ(γ+p\to p+ω)/dt$, in the near threshold region $E_γ\leq 2$ GeV. These sets of $ωNN$-coupling constants, corresponding to destructive and constructive $π\bigotimes N$-interference contributions to $dσ/dt$ can be well distinguished by measurements of beam asymmetry, induced by linear photon polarization. | |
