Systematic Regge theory analysis of omega photoproduction

Systematic analysis of available data for $omega$-meson photoproduction is given in frame of Regge theory. At photon energies above 20 GeV the $gamma{+}p{to}omega{+}p$ reaction is entirely dominated by Pomeron exchange. However, it was found that Pomeron exchange model can not reproduce the $gamma{+}p{to}rho{+}p$ and $gamma{+}p{to}omega{+}p$ data at high energies simultaneously with the same set of parameters. The comparison between $rho$ and $omega$ data indicates a large room for meson exchange contribution to $omega$-meson photoproduction at low energies. It was found that at low energies the dominant contribution comes from $pi$ and $f_2$-meson exchanges. There is smooth transition between the meson exchange model at low energies and Regge theory at high energies.
