摘要：

We show that a fully anticommuting γ5 is a correct and natural prescription for the dimensional regularization of one fermion loop graphs in spontaneously broken gauge theories. Other prescriptions introduce spurious anomalies into Ward identities which are actually anomly free. Our prescription is correct even though no such γ5 exists: it cannot exist precisely because of the familiar chiral anomaly. © 1979.
