Diffractive Dijet Photoproduction
Abstract
We have calculated diffractive dijet production in deep-inelastic scattering (DIS) at low-Q2 and next-to-leading order (NLO) of perturbative QCD, including contributions from direct and resolved photons. We study how the cross section depends on the factorization scheme and scale Mγ at the virtual photon vertex for the occurance of factorization breaking. The strong Mγ-dependence, which is present when only the resolved cross section is suppressed, is tamed by intodrucing the suppression also in the initial-state NLO correction of the direct part.
