Title: Photoproduction of J/psi mesons in the peripheral model. The diffraction mechanism

Abstract

An analysis is made of a mechanism for the photoproduction of J/psi mesons on nucleons with an imaginary amplitude that arises as the shadow of the amplitudes for the photoproduction of charmed particles. It is possible to describe the experimental data by means of this mechanism only if at moderate energies E/sub ..gamma../GeV a major role is played by processes involving the production of a charmed baryon and meson or a pair of charmed mesons in a resonant state, while at high energies the dominant processes involve the photoproduction of pairs of charmed mesons accompanied by hadrons, with a cross section that exceeds the cross section for the photoproduction of psi mesons by more than an order of magnitude.
