Abstract
We revisit the theoretical predictions for anomalous radiative decays
of pseudoscalar and vector mesons. Our analysis is performed in the
framework of the Nambu-Jona-Lasinio model, introducing adequate
parameters to account for the breakdown of chiral symmetry. The
results are comparable with those obtained in previous approaches.
