Abstract

Systematic analysis of available data for ω\omega-meson photoproduction is given in frame of Regge theory. At photon energies above 20 GeV the γ+pω+p\gamma{+}p{\to}\omega{+}p reaction is entirely dominated by Pomeron exchange. However, it was found that Pomeron exchange model can not reproduce the γ+pρ+p\gamma{+}p{\to}\rho{+}p and γ+pω+p\gamma{+}p{\to}\omega{+}p data at high energies simultaneously with the same set of parameters. The comparison between ρ\rho and ω\omega data indicates a large room for meson exchange contribution to ω\omega-meson photoproduction at low energies. It was found that at low energies the dominant contribution comes from π\pi and f2f_2-meson exchanges. There is smooth transition between the meson exchange model at low energies and Regge theory at high energies.
