A First Glimpse at Super-Leading Logarithms in Monte Carlo Evolution

Abstract

Super-leading logarithms from Glauber exchange complicate the resummation of non-global observables at hadron colliders. In this Letter, we extend Marzili, a Monte Carlo framework for non-global resummation based on effective field theory, to resum the leading nonzero colour contribution involving two Glauber exchanges. This is the first Monte Carlo resummation of super-leading logarithms. Together with Marzili's treatment of non-global logarithms, this opens a path towards studying their interplay and incorporating Glauber exchange into parton showers.
