Abstract: Diffractive photoproduction of dijets was measured with the ZEUS detector atthe ep collider HERA using an integrated luminosity of 77.2 pb-1. Themeasurements were made in the kinematic range Q^2 < 1 GeV^2, 0.20 < y < 0.85and x pom < 0.025, where Q^2 is the photon virtuality, y is the inelasticityand x pom is the fraction of the proton momentum taken by the diffractiveexchange. The two jets with the highest transverse energy, E T^jet, wererequired to satisfy E T^jet > 7.5 and 6.5 GeV, respectively, and to lie in thepseudorapidity range -1.5 < eta^jet < 1.5. Differential cross sections werecompared to perturbative QCD calculations using available parameterisations ofdiffractive parton distributions of the proton.
