Scattering Amplitudes in Three Dimensions

Lipstein, A (Oxford)
Tuesday 03 April 2012, 09:00-10:30

Seminar Room 1, Newton Institute


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.
