In this thesis, we have explored the rich phenomenology of the chiral anomaly in order to further our understanding of this fascinating and unique aspect of quantum field theory. We studied a subset of anomalous processes viz., [special characters omitted], and [special characters omitted] with the explicit purpose of extending the current status of calculations in this sector. For this, we applied the N/D formalism, which exploits the unitarity and analyticity of the scattering amplitude, in order to provide a plausible extension of one-loop results into resonance dominated regions of phase space. In particular, we were able to account for vector meson exchange effects by demanding that the phase shifts of the N/D function reflect those appearing in [special characters omitted]-scattering. We also compared our results with calculations based on vector dominance models, for which purpose we adopted the hidden symmetry approach.
