Abstract

Differential dijet cross sections have been measured with the ZEUS detector for photoproduction events in which the hadronic final state containing the jets is separated with respect to the outgoing proton direction by a large rapidity gap. The cross section has been measured asa function of the fraction of the photon (x(gamma)(OBS)) and pomeron (beta(OBS)) momentum participating in the production of the dijet system. The observed x(gamma)(OBS) dependence shows evidence for the presence of a resolved- as well as a direct-photon component. The measured cross section d sigma/d beta(OBS) increases as beta(OBS) increases indicating that there is a sizeable contribution to dijet production fromthose events in which a large fraction of the pomeron momentum participates in the hard scattering. These cross sections and the ZEUS measurements of the diffractive structure function carl be described by calculations ba-sed on parton densities ill the pomeron which evolve according to the QCD evolution equations and include a substantial hard momentum component of gluons in the pomeron.
