Axial Anomaly Effects in Pion and $Z^0$ Radiative Decays

Abstract

We discuss a connection between axial anomaly and polarized radiative processes. By comparison with the corresponding unpolarized cases, we consider some physical outputs for the ${\pi }^{+}$ and $Z^0$ polarized radiative decays. We analyse in detail the pattern of mass singularity cancellation.
