Radiative decays of $f_1(1285)$ as the $K^{\ast }\bar{K}$ molecular state

Abstract

Within a picture of the $f_1(1285)$ being a dynamically generated resonance from the $K^{\ast }\bar{K}$ interactions, we estimate the rates for the radiative transitions of the $f_1(1285)$ meson to the vector mesons ${\rho }^0$,$\omega$ and $\varphi$. These radiative decays proceed via the kaon loop diagrams. The calculated results are in fair agreement with the experimental measurements. Some predictions can be tested by experiments and their implementation and comparison with these predictions will be valuable to decode the nature of the $f_1(1285)$ state.
