Description
I present a new QCD description of the ATLAS jet veto measurement, using the Banfi-Marchesini-Smye equation to constrain the inter-jet QCD radiation. This equation resums emissions of soft gluons at large angles, at leading-logarithmic accuracy, and accounts for both the so-called Sudakov and non-global logarithms. I show that this approach is able to reproduce the fraction of high-pT forward/backward di-jet events which do not contain additional hard emissions in the inter-jet rapidity range.
