Probing BFKL dynamics in Mueller-Navelet jet production at the LHC

TL;DR

This paper investigates BFKL dynamics in Mueller-Navelet jet production at the LHC, demonstrating that next-to-leading order corrections improve theoretical descriptions of jet azimuthal correlations and address energy-momentum conservation issues.

Contribution

The study applies NLL BFKL calculations with optimized scale setting to better match LHC data and highlights the impact of NLO corrections on energy-momentum conservation in jet production.

Findings

Good agreement with CMS data for azimuthal correlations

NLO corrections reduce energy-momentum non-conservation effects

Scale fixing improves BFKL predictions

Abstract

We review the results of our studies on the production of two jets with a large interval of rapidity at hadron colliders, which was proposed by Mueller and Navelet as a possible test of the high energy dynamics of QCD, within the next-to-leading logarithm framework. The application of the Brodsky-Lepage-Mackenzie procedure to fix the renormalization scale leads to a very good description of the available CMS data at the LHC for the azimuthal correlations of the jets. We show that the inclusion of next-to-leading order corrections to the jet vertex significantly reduces the importance of energy-momentum non-conservation which is inherent to the BFKL approach, for an asymmetric jet configuration.
