Description
After a general introduction to explain the motivations of this research, I reconsider the Adler-Bardeen theorem and give a proof that is more general than the ones known so far. Among other things, it identifies the subtraction scheme where gauge anomalies manifestly cancel to all orders, if they vanish at one loop. Differently from most other proofs, mine does not make use of renormalization-group techniques, therefore it applies to all perturbatively unitary, power counting renormalizable quantum field theories, including conformal and finite theories.
