Geometric Scaling in Mueller-Navelet Jets

TL;DR

This paper discusses how Mueller-Navelet jet production at the LHC can be used to study gluon saturation and high energy scattering, highlighting geometric scaling behavior and the impact of non-perturbative effects on cross sections.

Contribution

It demonstrates that Mueller-Navelet jets exhibit geometric scaling in their cross sections and analyzes the influence of running coupling and non-perturbative physics.

Findings

Cross section shows geometric scaling in a suitable transverse momentum range.

Non-perturbative physics affects normalization but not scaling behavior.

Running coupling complicates perturbative calculations of jet production.

Abstract

We argue that the production of Mueller-Navelet jets at the LHC represents a convenient environment to study gluon saturation and high energy scattering in the presence of unitarity corrections. We show that, in a suitable range of transverse momenta for the produced jets, the cross section for the partonic subprocess should exhibit geometric scaling. We point out that, in the presence of a running coupling, the cross section for producing hard jets cannot be fully computed in perturbation theory, not even after taking into account the saturation effects: the non-perturbative physics affects the overall normalization of the cross section, but not also its geometric scaling behavior.
