Scattering Amplitudes in Three Dimensions

Presented by: 
A Lipstein [Oxford]
Date: 
Tuesday 3rd April 2012 - 09:00 to 10:30
Venue: 
INI Seminar Room 1
Abstract: 
A great deal of progress has been made in computing scattering amplitudes in 4d quantum field theories by expressing the amplitudes in terms of variables known as twistors. In this talk, I will describe twistorial methods for computing scattering amplitudes in 3d quantum field theories, in particular superconformal Chern-Simons theories and supersymmetric Yang-Mills theories. These methods have led to the discovery of new symmetries and dualities in 3d quantum field theories.
