Abstract

A Lorentz and gauge symmetry preserving regularization method has been proposed recently in four dimensions based on Euclidean momentum cutoff. It is shown that the triangle anomaly can be calculated unambiguously with this new improved cutoff. The anticommutator of γ5 and γμ multiplied by five γ matrices is proportional to terms that do not vanish under a divergent loop-momentum integral, but cancel otherwise.
