### Event details

Abstract: It is well-known that scattering amplitudes in quantum field theory contain "infrared divergences" associated with the emission of force-carrying particles (e.g. photons, gluons and gravitons) at large distances. Understanding these divergences is interesting in its own right, but also allows us to increase the precision of calculations at hadron colliders such as the Tevatron and the LHC. This talk will summarise recent developments concerning IR behaviour in QCD. I will also look at intriguing relationships between QCD and quantum gravity, which the infrared limit helps to clarify.

### About Particle Physics Theory seminars

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
