Dijets in Photoproduction

Gilles Frising

Dijet cross sections as functions of several jet observables are measured in photoproduction using the H1 detector at HERA. The data sample comprises ep data with an integrated luminosity of 34.9 pb-1. Jets are selected using the inclusive kt algorithm with a minimum transverse energy of 25 GeV for the leading jet. The phase space covers longitudinal proton momentum fraction xp and photon longitudinal momentum fraction x\gamma in the ranges 0.05< xp<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.
