Abstract
The dijet cross section in photoproduction ha's been measured with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb(-1). The events were required to have a virtuality of the incoming photon, Q(2), of less than 1 GeV2 and a photon-proton centre-of-mass energy in the range 131 < W-yp < 277 GeV. Each event contains at least two jets satisfying transverse-energy requirements of E-T(jet1) > 14 GeV and E-T(jet2) > 11 GeV and pseudorapidity requirements of -1 < eta(jet1,2) < 2.4. The measurements arc compared to next-to-loading-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.
