Systematic Regge theory analysis of ω photoproduction

Abstract

Systematic analysis of available data for ω-meson photoproduction is given in the framework of the Regge theory. At photon energies above 20 GeV the γ+p→ω+p reaction is entirely dominated by Pomeron exchange. However, it was found that Pomeron exchange model cannot reproduce the γ+p→ρ+p and γ+p→ω+p data at high energies simultaneously with the same set of parameters. The comparison between ρ and ω data indicates a large room for meson exchange contribution to ω-meson photoproduction at low energies. It was found that at low energies the dominant contribution comes from π- and f2-meson exchanges. There is smooth transition between the meson exchange model at low energies and the Regge theory at high energies.
