Within a picture of the $f_1(1285)$ being a dynamically generated resonance from the $ K^*\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 $\phi$. 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.

$f_1(1285)$ 作为 $ K^*\bar K$ 分子态的辐射衰变

在 $f_1(1285)$ 是 $ K^*\bar K$ 相互作用的动态共振的图片中,我们估计了 $f_1(1285)$ 介子到矢量介子的辐射跃迁率\rho^0$、$\omega$ 和 $\phi$。这些辐射衰减通过 kaon 回路图进行。计算结果与实验测量结果基本一致。一些预测可以通过实验进行测试,它们的实现以及与这些预测的比较对于解码 $f_1(1285)$ 状态的性质是有价值的。
