Measurement of dijet cross sections in photoproduction at HERAThe 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 algorithm with a minimum transverse energy of for the leading jet. The phase space covers longitudinal proton momentum fraction xp and photon longitudinal momentum fraction in the ranges 0.05<xp<0.6 and . 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.
