Exploring the Pomeron with Jet-gap-Jet observables at the LHC

We give a broad introduction to the Pomeron in QCD and related theories and discuss its role in the description of the total cross-section and diffractive events. Originally introduced in Regge-theory, to describe the observed rise of the total hadronic cross-section, the Pomeron is at first of non-perturbative origin. A microscopic description in terms of quarks and gluons is provided by the so-called hard or Balitsky-Fadin-Kuraev-Lipatov (BFKL)-Pomeron. After a general introduction and a review of potential signals of the hard Pomeron at past, present and future collider experiments, we present in this talk as a new result the forward jet vertex associated to a rapidity gap in the BFKL formalism at next-to-leading order (NLO). This result is important since it allows, together with the NLO non-forward gluon Green function, to perform NLO studies of jet production in diffractive events, such as so-called Mueller-Tang dijets.
