Abstract. We calculate diffractive dijet production in deep-inelastic scattering at next-to-leading order of perturbative QCD, including contributions from direct and resolved photons, and compare our predictions to preliminary data from the H1 collaboration at HERA. We study how the cross section depends on the factorization scheme and scale M γ at the virtual photon vertex for the occurrence of factorization breaking. The strong M γ -dependence, which is present when only the resolved cross section is suppressed, is tamed by introducing the suppression also into the initial-state NLO correction of the direct part.

“…In the Resolved-Pomeron model [8], the diffractive scattering is factorised into a Pomeron flux from the proton and the hard interaction between the virtual photon and a constituent parton of the Pomeron. An example of such a process is shown in Fig.…”

“…The former quantity is defined as β = x/x IP , where x is the Bjorken variable and x IP is the fractional loss of proton longitudinal momentum. The results of this analysis are compared to predictions from the Two-Gluon-Exchange model [6,7] and the Resolved-Pomeron model of Ingelman and Schlein [8].…”

Production of exclusive dijets in diffractive deep inelastic e ± p scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 372 pb -1 . The measurement was performed for γ * -p centre-of-mass energies in the range 90 < W < 250 GeV and for photon virtualities Q 2 > 25 GeV 2 . Energy and transverse-energy flows around the jet axis are presented. The cross section is presented as a function of β and φ , where β = x/x IP , x is the Bjorken variable and x IP is the proton fractional longitudinal momentum loss. The angle φ is defined by the γ * -dijet plane and the γ * -e ± plane in the rest frame of the diffractive final state. The φ cross section is measured in bins of β . The results are compared to predictions from models based on different assumptions about the nature of the diffractive exchange.

The cross section of the diffractive process ep → eX p is presented where the system X contains at least two jets and the leading final state proton is tagged in the H1 Very Forward Proton Spectrometer (VFPS). The measurement is performed for photoproduction with Q 2 < 2 GeV 2 in photon virtuality and for deep-inelastic-scattering with 4 GeV 2 < Q 2 < 80 GeV 2 . Measured cross sections are compared to next-to-leading order QCD calculations based on diffractive parton distribution functions extracted from measurements of inclusive cross sections in diffractive deep-inelasticscattering. The results are discussed with focus on the validity of the factorisation theorem for these processes.
