Description

In 2006, Jeff Forshaw, Albrecht Kyrieleis and I published a paper in which we identified a tower of super-leading (relative to the single logarithmic series that was expected to be leading) logarithms in non-global observables and discussed their origin as a breakdown of QCD coherence, and possibly of factorization. In this historical talk, I will recall the work that led up to this paper, the reaction to it and some of the further work it stimulated.
