Super-leading logarithms in non-global observables in QCD: Fixed order calculation

High Energy Physics - Phenomenology 2010-04-21 v1

Abstract

Super-leading logarithmic terms have previously been observed in non-global QCD observables. In this paper we re-calculate the first super-leading contribution to the `gaps between jets' cross-section using a diagrammatic fixed order approach. We calculate for the first time the super-leading contribution at fifth order in alpha_s.
