Recently, the BESIII Collaboration reported two new decay processes: and . Inspired by this measurement, we propose to study the radiative decays of via intermediate charmed meson loops in an effective Lagrangian approach. With the acceptable cutoff parameter range, the calculated branching ratios of and are of the orders of to and to , respectively. The ratio can reproduce the experimental measurements with the commonly acceptable range. This ratio provide us with some information on the – mixing, which may be helpful for us to test the SU(3)-flavor symmetries in QCD.
