Measurement of dijet cross sections in photoproduction at HERA

The H1 Collaboration

(Received: 4 January 2002 / Published online: 12 July 2002 )

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 $25~\,\mbox{GeV}$ 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.
