Abstract

BRST anomalies arising from modular integrations can be cancelled between different genus world-sheets at the price of moving the world-sheet σ-model away from its conformal fixed point. We have fully implemented this procedure for the lowest-loop corrections to the type-I superstring. The associated conformal invariance violations are responsible for important corrections to the background field equations including both the coupling of the gauge field to gravity and the anomaly-cancelling interactions of the antisymmetric tensor field.
