Breakdown of Coherence ?

Understand

In a recent paper, Albrecht Kyrieleis, Jeff Forshaw and I discovered a new tower of super-leading logarithms in gaps between jets cross sections.

• After discussions with the referee of our paper and further investigation, we have come to view this as a breakdown of naive coherence for initial state radiation.
• In this talk I illustrate this statement in a simple way, and show how it results in the super-leading logarithms.
