The Role of $\gamma_5$ in Dimensional Regularization
Dirk Kreimer · arXiv (Cornell University) · 1994
We discuss the consistency of a new \gf -scheme with renormalization. In particular we study the power-counting behaviour of multiloop graphs to prove its consistency. As a side effect we obtain a short proof of the Adler-Bardeen theorem. Further we show that this \gf-scheme does not modify the BRST identities at any loop orders in contrast to BM type schemes.
