Contribution

It provides the first complete NLO correction to the Mueller-Tang impact factor within the high energy effective action framework.

Findings

Complete NLO real part of the impact factor determined.

Enhances the precision of BFKL-based predictions for dijet events.

Progress towards a full NLO BFKL description of rapidity gap processes.

Abstract

We report on recent progress in the evaluation of next-to-leading order observables using Lipatov's QCD high energy effective action. In this contribution we focus on the determination of the real part of the next-to-leading order corrections to the Mueller-Tang impact factor which is the only missing element for a complete NLO BFKL description of quark induced dijet events with a rapidity gap.
