. .UNIVERSITAT BONNPhysikalisches InstitutDijets in Di ractiv e Photoproductionmeasured with the ZEUS ExperimentbyRoger RennerThe di ractiv e photoproduction of dijets in electron-proton scatter-1ing has been studied using 77:1 pb of data taken with the ZEUSdetector at HERA. The measurements have been made at a centre-pof-mass energy s = 318 GeV in the kinematic range 0:2 < y < 0:85and x < 0:025, where y is the inelasticity and x is the fractionIP IPof the proton momentum taken by the di ractiv e exchange. Thejets have been reconstructed using the k algorithm. The two jetsTwith the highest transversal energy have been required to satisfyE > 7:5 and 6:5 GeV, respectively, and to be in the pseudorapidityTrange 1:5 < < 1:5. Di eren tial cross sections have been measuredand been confronted with the predictions from leading order MonteCarlo simulations and next-to-leading order QCD calculations.Post address: BONN-IR-2006-13Nu allee 12 Bonn University53115 Bonn Oktober 2006Germany ISSN-0172-8741. .UNIVERSITAT BONNPhysikalisches InstitutDijets in Di ractiv e Photoproductionmeasured with the ZEUS ExperimentvonRoger RennerDieser Forschungsbericht wurde als Dissertation von der Mathematisch-Naturwissenschaftlichen Fakult at der Universit at Bonn angenommen.Referent: Prof. Dr. E.
