Abstract.
Dijet cross sections as functions of several jet observables are measured in photoproduction using the H1 detector at HERA. The data sample comprises \(e^+p\) data with an integrated luminosity of 34.9 pb\(^{-1}\). Jets are selected using the inclusive \(k_{\bot}\) algorithm with a minimum transverse energy of 25 GeV for the leading jet. The phase space covers longitudinal proton momentum fraction \(x_p\) and photon longitudinal momentum fraction \(x_\gamma\) in the ranges \(0.05 < x_p < 0.6\) and \(0.1 < x_{\gamma} < 1\). The predictions of next-to-leading order perturbative QCD, including recent photon and proton parton densities, are found to be compatible with the data in a wide kinematical range.
