The axial-anomaly puzzle in supersymmetry gauge theories
Vainshtein A. I. , Zakharov V. I. , Novikov V. A. , Shifman M. A.
It is shown ίη η = 1 supersymmetry gauge theories that it is not possible to introduce an axial current which would be a superpartner of the energy-momentum tensor and which would belong to the same supermultiplet as the latter. The arguments are based on extremely weak assumptions: the Adler-Bardeen theorem in two loops and the existence of a Wess-Zumino supergauge.
