Mueller-Navelet jets at the LHC

TL;DR

This paper presents a next-to-leading logarithmic BFKL analysis of Mueller-Navelet jets at the LHC, successfully comparing with CMS data, and discusses the importance of asymmetric jet measurements and the negligible impact of double parton scattering.

Contribution

It provides a complete NLL BFKL analysis with BLM scale fixing and emphasizes the need for asymmetric jet measurements for better theory-data comparison.

Findings

NLL BFKL analysis agrees with CMS data

Energy-momentum violation is minimal in asymmetric configurations

Double parton scattering is negligible in current measurements

Abstract

We report on our NLL BFKL studies of Mueller-Navelet jets. We first perform a complete NLL BFKL analysis supplemented by a BLM renormalization scale fixing procedure, which is successfully compared with recent CMS data. Second, we argue for the need of a measurement of an asymmetric jet configuration in order to perform a valuable comparison with fixed order approaches. Third, we predict that the energy-momentum violation is rather tiny in the NLL BFKL approach, for an asymmetric jet configuration. Finally, we argue that the double parton scattering contribution is negligible in the kinematics of actual CMS measurements.
