We study the decay of dynamically generated resonances from the interaction of two vectors into a γ and a pseudoscalar meson. The dynamics requires anomalous terms involving vertices with two vectors and a pseudoscalar, which renders it special. We compare our result with data on K∗+(1430)→K+γ and K∗0(1430)→K0γ and find a good agreement with the data for the K∗+(1430) case and a width considerably smaller than the upper bound measured for the K∗0(1430) meson. |
