Azimuthal-angle Observables in Inclusive Three-jet Production

TL;DR

This paper investigates azimuthal-angle observables in three-jet production at the LHC, assessing how higher-order corrections influence their effectiveness in probing BFKL dynamics.

Contribution

It extends the analysis of azimuthal-angle ratios to include corrections beyond leading-logarithmic accuracy in a three-jet setup.

Findings

Corrections beyond leading order are mild, indicating robustness of the observables.

Azimuthal-angle ratios remain effective probes of BFKL effects.

The extended setup enhances the potential to study QCD dynamics at colliders.

Abstract

We discuss the impact of corrections beyond the leading-logarithmic accuracy on some recently proposed LHC observables that are based on azimuthal-angle ratios in a kinematical setup that is an extension to the usual one for Mueller-Navelet jets, after requiring an extra tagged jet in central regions of rapidity. The corrections tend to be mild which suggests that these observables are an excellent way to probe the onset of BFKL effects at hadronic colliders.
