Regge theory for correlation functions in CFTs
Vasco Goncalves
(U. do Porto)
Abstract:
In this talk we will try to motivate why the study of the Regge limit in a correlation function of a conformal field theory is interesting. We will review the results obtained in the past few years and present some on going work in phi^3 theory using skeleton expansion.

From gluons to gravitons in the soft limit
Chris White
(Glasgow)
Abstract:
It is well-known that infrared singularities arise in scattering amplitudes due to the emission of soft (low energy) gluons and / or gravitons. These are important for collider predictions, but also give us all-order insights into perturbation theory. This talk will review a number of recent developments in this area, such as: the structure of IR singularities in multiparton scattering amplitudes; the relationship between Yang-Mills theory and gravity in the soft limit; the classification of amplitudes beyond the soft approximation.
