Abstract
Witten's linear sigma model for ADHM instantons possesses a natural supersymmetry. We study generalizations of the infrared limit of the model that are invariant under supersymmetry. In the case of four space-time dimensions a background with a conformally flat metric and torsion is required. The geometry is specified by a single real scalar function satisfying Laplace's equation. It gives rise to 't Hooft instantons for the gauge group , instead of the general ADHM instantons for an gauge group in the case .
