Super-leading logarithms in gaps-between-jets

Abstract

We identify a source of super-leading logarithms in the gaps-between-jets observable at hadron colliders. These new contributions are expected to generally appear in non-global observables in QCD and are connected with the presence of Coulomb phase terms.
