Twistor sigma models

<p>This thesis presents an overview of recent developments in the applications of twistor theory to the study of the gravitational S-matrix in flat as well as curved space-times. We begin by introducing the novel geometric tool of twistor sigma models. These are two-dimensional chiral sigma mo...
