Abstract
We discuss a connection between axial anomaly and polarized radiative proce sses. By comparison with the corresponding unpolarized cases, we consider s ome physical outputs for the pi(+) and Z(0) polarized radiative decays. We analyse in detail the pattern of mass singularity cancellation. (C) 2000 El sevier Science B.V. All rights reserved.
