Contribution

It presents a novel model combining BFKL Pomeron with soft radiation simulation to describe jet-gap-jet events in hadron collisions.

Findings

Model reproduces Tevatron data accurately

Allows estimation of jet-gap-jet cross sections at LHC

Incorporates next-to-leading logarithmic corrections

Abstract

We propose a model to describe diffractive events in hadron-hadron collisions where a rapidity gap is surrounded by two jets. The hard color-singlet object exchanged in the t-channel and responsible for the rapidity gap is described by the pQCD Balitsky-Fadin-Kuraev-Lipatov Pomeron, including corrections due to next-to-leading logarithms. We allow the rapidity gap to be smaller than the inter-jet rapidity interval, and the corresponding soft radiation is modeled using the HERWIG Monte Carlo. Our model is able to reproduce all Tevatron data, and allows to estimate the jet-gap-jet cross section at the LHC.
