The High Energy Limit of QCD: BFKL Cross Sections

TL;DR

This paper discusses the detailed construction of BFKL cross sections in QCD, emphasizing next-to-leading order effects such as coherence, collinear improvements, jet production, and azimuthal decorrelations at colliders.

Contribution

It provides a comprehensive analysis of next-to-leading order corrections and effects in BFKL cross sections relevant for high-energy QCD processes.

Findings

Enhanced understanding of QCD coherence in DIS

Improved collinear region modeling in multi-Regge kinematics

Quantitative insights into azimuthal decorrelations of Mueller-Navelet jets

Abstract

In this contribution we describe in some detail different aspects of the construction of BFKL cross sections. We focus on several effects which are relevant at next-to-leading order. In particular, we describe QCD coherence in DIS final states, improvements of the collinear region in multi-Regge kinematics, inclusive jet production at next-to-leading order, and azimuthal angle decorrelations of Mueller-Navelet jets at hadron colliders.
