Multi-Jet Processes in the High Energy Limit of QCD

Andersen, Jeppe R.

Abstract

We discuss how the multi-Regge factorisation of QCD amplitudes can be used in the study of multi-jet processes at colliders. We describe how the next-to-leading logarithmic (NLL) BFKL evolution can be combined with energy and momentum conservation. By recalculating the quark contribution to the next-to-leading logarithmic corrections to the BFKL kernel we can study several properties of the NLL corrections. We demonstrate that in the standard analysis, the NLL corrections to a single gluon emission includes contributions from significantly more energetic quark--anti-quark configurations, something that could contribute to the sizable NLL corrections in the standard BFKL analysis.
