Twistor inspired techniques for gauge theory amplitudes

We examine recent developments in perturbative calculations of gauge theory amplitudes.

Description
Summary:We examine recent developments in perturbative calculations of gauge theory amplitudes. Motivated by a twistor space analysis, Cachazo, Svrcek and Witten (CSW) formulated a new set of rules for computing scattering amplitudes, which have now been dubbed the CSW rules. We examine the origins of these rules, and apply them to supersymmetric and non-supersymmetric gauge theories. We review many of the recent calculations performed using this new prescription at both the tree and one-loop levels. === Science, Faculty of === Physics and Astronomy, Department of === Graduate
