Abstract
The possibility to measure jet-gap-jet final states in double-Pomeron-exchange events at the LHC is presented. In the context of the ATLAS experiment with additional forward physics detectors, cross sections for different experimental settings and gap definitions are estimated. This is done in the framework of the forward physics Monte Carlo interfaced with a perturbative QCD model that successfully reproduces standard jet-gap-jet cross sections at the Tevatron. The extrapolation to LHC energies follows from the Balitsky-Fadin-Kuraev-Lipatov dynamics, implemented in the model at next-to-leading logarithmic accuracy.
Highlights
In a hadron-hadron collision, a jet-gap-jet event features a large rapidity gap with a high-pT jet on each side
In [6], the resulting parton-level hard cross section was interfaced with the HERWIG
Monte Carlo [7], as was first proposed in [8] in the case of the leading-logarithm (LL) BFKL calculation, in order to take into account parton showering, hadronization, and jet reconstruction effects
Summary
In a hadron-hadron collision, a jet-gap-jet event features a large rapidity gap with a high-pT jet on each side We propose to take advantage of the future ATLAS Forward Proton (AFP) detector [12], in order to realize a true jet-gap-jet measurement. In this context, one would look for jet-gap-jet final states in double-Pomeron-exchange (DPE) processes, with both protons intact. We define a gap to be a rapidity interval devoid of tracks with transverse momentum bigger than 200 MeV, for this reason we shall restrict ourself to central gaps, within the ATLAS tracker acceptance The modeling of such events can be obtained by implementing the parton-level.
