Description
We investigate the infrared interpretation of the axial anomaly in QED, by using the dispersive method. We also study this aspect by examining how the axial anomaly is produced in the Schwinger model. Following the interpretation of the physical meaning of this phenomenon, as it emerges in the dispersive approach, we find a manifestation of the axial anomaly in radiative polarized processes. Finally, we analyze the mechanism of mass singularity cancellation in these processes
