The photoproduction cross section for high-E dijets has been measured using the ZEUS detector at HERA using an integrated luminosity of 81.8 pb-1. The events were required to have a virtuality of the incoming photon, Q2, of less than 1 GeV2 and a photon-proton centre-of-mass energy in the range 142 15 GeV and pseudorapidity requirements of 1 < Vi,2 < 3 with at least one of the jets satisfying 1 < rj < 2.5. These data have been used to further constrain the parton densities in the proton. The measurements are compared to next-to-leading order QCD predictions and show sensitivity to the choice of the parton densities in the photon and to the effects of higher orders.
