Evaluating gauge-theoretic amplitudes with twistor diagrams

Andrew Hodges
(Oxford)
Abstract
 
Amplitudes in gauge theory at tree-level can be expressed economically in terms of twistor diagrams  (hep-th/0503060, hep-th/0512336). This formalism has recently been used to write down the 8-field scattering amplitudes in a simple form, going beyond the results previously obtained (hep-th/0603101). This talk will give an elementary account of how this is done.
