On Closed Twistor String Theory

Abstract

The Heterotic twistor string theory of Mason and Skinner is investigated with particular attention given to the role of topological gravity on the world-sheet. The general structure of scattering amplitudes is discussed and expressed in terms of an integral over the moduli space of super Riemann surfaces.
