Abstract (summary)

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.
