Abstract: | The dijet cross section in photoproduction has been measured with the ZEUS detector at HERA using an integrated luminosity
of 38.6 pb. The events were required to have a virtuality of the incoming photon, , of less than 1 GeV and a photon-proton centre-of-mass energy in the range GeV. Each event contains at least two jets satisfying transverse-energy requirements of GeV and GeV and pseudorapidity requirements of \mbox{}. The measurements are compared to next-to-leading-order QCD predictions. The data show particular sensitivity to the density
of partons in the photon, allowing the validity of the current parameterisations to be tested.
