The axial current in dimensional regularization

  • 1. California Univ., Berkeley (USA). Lawrence Berkeley Lab.

Description

It is shown 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 anomaly free. The prescription is correct even though no such γ5 exists; it cannot exist precisely because of the familiar chiral anomaly. (Auth.)
