Abstract

With as a dynamically generated resonance from interactions, we estimate the rates of the radiative transitions of the meson to the vector mesons , and . These radiative decays proceed via the kaon loop diagrams. The calculated results are in a fair agreement with experimental measurements. Some predictions can be tested experimentally; their analysis will be valuable for decoding the strong coupling of the state to the channel.
