An Effective Theory for Jet Processes

by Thomas Becher

Abstract: Processes involving narrow jets receive perturbative corrections enhanced by logarithms of the jet opening angle and the ratio of the energies inside and outside the jets. In my talk I’ll present a new effective field theory which fully separates the physics at the different energy scales relevant in such processes. This makes it for the first time possible to systematically resum logarithmically enhanced corrections to jet cross sections to all orders.
