Isospin breaking effects in the anomalous processes with vector mesons

We introduce isospin/SU(3) breaking terms in the anomalous WP coupling in the hidden local symmetry scheme without affecting the low-energy theorem. It is shown that the predictions from these terms coincide successfully with all the experimental data of anomalous decays. It is also predicted that the decay widths of ϱ0 → π0γ and f → η′γ are 114 ± 7 keV and 0.55 ± 0.055 keV, respectively.
