Extended anomaly cancellation mechanisms to brane-antibrane systems

Applied these mechanisms to ten-dimensional string theories with D-branes

Analyzed anomaly cancellation in supersymmetric compactifications

Abstract

String theories with branes can often be generalized by adding brane-antibrane pairs. We explore the cancellation of anomalies in this more general context, extending the familiar anomaly-cancelling mechanisms, both for ten-dimensional string theories with D-branes and for certain supersymmetric compactifications.
