  We show that isospin/SU(3) breaking terms can be introduced to the anomalous
VVP coupling in the hidden local symmetry scheme without changing
Wess-Zumino-Witten term in the low-energy limit. We make the analysis for
anomalous processes of 2-body and 3-body decays; radiative vector meson
decays(V \to P\gamma), conversion decays of photon into a lepton pair(V \to P
l^+ l^-) and hadronic anomalous decays(V \to PPP). The predictions successfully
reproduce all experimental data of anomalous decays. In particular, we predict
the decay widths of \rho^0 \to \pi^0 \gamma and \phi \to \eta' \gamma as 101
\pm 9 keV and 0.508 \pm 0.035 keV, respectively, which will be tested in the
DAFNE \phi-factory. Moreover, prediction is also made for \phi \to \pi^0 e^+
e^-, \rho \to 3\pi, K^* \to K \pi \pi and so on, for which only the
experimental upper bounds are available now.
