“…In the DIS regime, the theoretical expectation agrees with the measurement within uncertainties. This confirms the observation made in previous measurements [8][9][10][11]. In contrast, the integrated diffractive dijet cross section in photoproduction is overestimated by the NLO QCD theory by almost a factor of two, with considerable theory uncertainty.…”

Abstract:The cross section of the diffractive process e + p → e + Xp is measured at a centre-of-mass energy of 318 GeV, where the system X contains at least two jets and the leading final state proton p is detected in the H1 Very Forward Proton Spectrometer. The measurement is performed in photoproduction with photon virtualities Q 2 < 2 GeV 2 and in deep-inelastic scattering with 4 GeV 2 < Q 2 < 80 GeV 2 . The results are compared to nextto-leading order QCD calculations based on diffractive parton distribution functions as extracted from measurements of inclusive cross sections in diffractive deep-inelastic scattering.

“…Given the DPDFs, perturbative QCD calculations are expected to be applicable to other processes such as jet and heavy quark production in DDIS at HERA [6][7][8][9][10][11]. Indeed, next-to-leading order (NLO) QCD predictions using DPDFs describe these measurements well.…”

“…This difference between low and high-p t samples will be clearly visible in the final results. 12 The choice of a cut on pt1 was originally motivated by the observation in the context of HERA [96][97][98] that identical simultaneous cuts on pt1 and pt2 led to poor convergence of the perturbative series, for reasons discussed in [99,100]. Cutting on pt1 was intended as a way of avoiding this problem, but, as we see here, seems to introduce issues of its own.…”

We present results for matched distributions of a range of dijet event shapes at hadron colliders, combining next-to-leading logarithmic (NLL) accuracy in the resummation exponent, next-to-next-to leading logarithmic (NNLL) accuracy in its expansion and next-to-leading order (NLO) accuracy in a pure α s expansion. This is the first time that such a matching has been carried out for hadronic final-state observables at hadron colliders. We compare our results to Monte Carlo predictions, with and without matching to multi-parton tree-level fixed-order calculations. These studies suggest that hadron-collider event shapes have significant scope for constraining both perturbative and non-perturbative aspects of hadron-collider QCD. The differences between various calculational methods also highlight the limits of relying on simultaneous variations of renormalisation and factorisation scale in making reliable estimates of uncertainties in QCD predictions. We also discuss the sensitivity of event shapes to the topology of multi-jet events, which are expected to appear in many New Physics scenarios.

“…Diffractive jet production in DIS has been studied by both the H1 and ZEUS Collaborations [21][22][23]. The kinematic range of the photon virtuality is 4 < Q 2 < 80 GeV 2 for the H1 and 5 < Q 2 < 100 GeV 2 for the ZEUS analyses.…”

A. Bunyatyan a (on behalf of the H1 and ZEUS collaborations)a DESY, MPI für Kernphysik, Heidelberg and Yerevan Physics InstituteThe high centre-of-mass energies of the HERA ep collider and of the Tevatron collider allow us to study the diffractive interactions in the presence of a hard scale and to describe them in terms of perturbative QCD. In QCD, the diffractive exchange is described in terms of partons, and the factorisation theorem states that the cross section for hard interactions can be expressed as convolution of universal diffractive parton distribution functions and process-dependent coefficients, perturbatively calculable. The recent experimental data from the H1 and ZEUS Collaborations at HERA are presented for diffractive dijet and D * meson production, in both deep-inelastic scattering (DIS) and the photoproduction regimes and are compared to next-to-leading order QCD predictions using diffractive parton distributions. While good agreement is found for dijets in DIS and for D * production in both DIS and photoproduction, the dijet photoproduction data are overestimated by NLO predictions at lower transverse momentum of the jets, indicating the breaking of QCD factorisation.
