Final state interactions in omega photoproduction near threshold

Abstract

Vector meson photoproduction and electroproduction have been suggested as a tool to find or confirm the nucleon resonances. In order to extract more reliable informations on the nucleon resonances, understanding the non-resonant background is indispensable. We consider final state interactions in omega photoproduction as a background production mechanism. For the intermediate states, we consider nucleon--vector-meson and nucleon-pion channels. The role of the final state interactions is discussed in omega meson photoproduction near threshold.
