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.
