Findings

BFKL predictions agree with Tevatron data

Predictions for LHC events are provided

Monte Carlo implementation improves modeling accuracy

Abstract

We investigate diffractive events in hadron-hadron collisions, in which two jets are produced and separated by a large rapidity gap. Using a renormalisation-group improved NLL kernel implemented in the HERWIG Monte Carlo program, we show that the BFKL predictions are in good agreement with the Tevatron data, and present predictions which could be tested at the LHC.
