Abstract
Using a Weyl transformation in superspace, we provide a noncanonical formulation of standard D=10, N=1 supergravity, including the gauge matter sector. This formulation turns out to be ideally suited for carrying out the renormalization of the Green-Schwarz σ-model describing the D=10 heterotic string propagating in a curved background space. By reducing the superspace results to the component level, we derive the supersymmetry transformation laws for the component fields of the theory.
