Title: Diffractive J/{psi} photoproduction in a dual model

Abstract

J/{psi} photoproduction is studied in the framework of the analytic S-matrix theory. The differential and integrated elastic cross sections for J/{psi} photoproduction are calculated from a dual amplitude with Mandelstam analyticity. It is argued that, at low energies, the background, which is the low-energy equivalent of the high-energy diffraction, replaces the Pomeron exchange. The onset of the high-energy Pomeron dominance is estimated from the fits to the data.
