Gaps between jets in double-Pomeron-exchange processes at the LHC

Understand

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.
