“…Experiments at the Tevatron and at HERA have already examined a variety of these large t diffractive processes, the most inclusive of which is the double dissociation process γp → X Y which has been studied at HERA [3]. 2 The gaps-betweenjets process, in which systems X and Y are each required to contain at least one jet, have been studied both at the Tevatron [4][5][6][7] and at HERA [8,9]. Additionally, the vector meson production process, γp → V Y , in which the system X is a single vector meson, V , has been measured at HERA [10,11].…”

We have performed a detailed phenomenological investigation of the hard colour singlet exchange process which is observed at the Tevatron in events which have a large rapidity gap between outgoing jets. We include the effects of multiple interactions to obtain a prediction for the gap survival factor. Comparing the data on the fraction of gap events with the prediction from BFKL pomeron exchange we find agreement provided that a constant value of α s is used in the BFKL calculation. Moreover, the value of α s is in line with that extracted from measurements made at HERA.

The jet energies are corrected using p T and η dependent jet energy scale (JES) calibration factors derived from simulated MC events [46].…”

“…Dijet production with a veto on additional hadronic activity in the rapidity interval between the jets has previously been studied at HERA [1][2][3] and the Tevatron [4][5][6][7][8]. The Large Hadron Collider (LHC) offers the opportunity to study this process at an increased centreof-mass energy and with a wider coverage in rapidity between jets.…”

A measurement of jet activity in the rapidity interval bounded by a dijet system is presented. Events are vetoed if a jet with transverse momentum greater than 20 GeV is found between the two boundary jets. The fraction of dijet events that survive the jet veto is presented for boundary jets that are separated by up to six units of rapidity and with mean transverse momentum 50 < p T < 500 GeV. The mean multiplicity of jets above the veto scale in the rapidity interval bounded by the dijet system is also presented as an alternative method for quantifying perturbative QCD emission. The data are compared to a next-to-leading order plus parton shower prediction from the powheg-box, an all-order resummation using the hej calculation and the pythia, herwig++ and alpgen event generators. The measurement was performed using pp collisions at √ s = 7 TeV using data recorded by the ATLAS detector in 2010.

“…The leading contribution to this process comes from the elastic scattering of partons via colour singlet exchange; the outgoing partons hadronise to produce the jets which are seen. Experiments at FNAL and HERA have reported their first results on the fraction of all dijet events which contain a gap in rapidity [ 5,6,7,8]. For rapidities greater than about 3 units between the jet centres, all see a clear excess of rapidity gap events over the number expected in the absence of a strongly interacting colour singlet exchange.…”
