Anomalies of the SO(32) five-brane and their cancellation Original Research Article

The anomaly due to the chiral fermions on the world-volume of the SO(32) five-brane is calculated. It is shown that this contribution has the correct structure for it to be cancelled by the variation of the classical world-volume action. The cancellation mechanism requires a Green-Schwarz-like term in the classical action. The result confirms the field content of the SO(32) five-brane proposed by Witten.
