# Anomalies in quantum field theory: Properties and characterization

@article{Kraus2002AnomaliesIQ, title={Anomalies in quantum field theory: Properties and characterization}, author={Elisabeth Kraus}, journal={arXiv: High Energy Physics - Theory}, year={2002} }

We consider the Adler-Bardeen anomaly of the U(1) axial current in abelian and non-abelian gauge theories and present its algebraic characterization as well as an explicit evaluation proving regularization scheme independence of the anomaly. By extending the gauge coupling to an external space-time dependent field we get a unique definition for the quantum corrections of the topological term. It also implies a simple proof of the non-renormalization theorem of the Adler-Bardeen anomaly. We…
