We use the method of QCD sum rules in the presence of the external electromagnetic Fμν field to analyze radiative decays of charmed or bottomed mesons such as D*→ Dγ and B*→ Bγ, in a model-independent manner upon making use of the susceptibilities obtained previously from the study of baryon magnetic moments. Our predictions on D* decays agree very well with the experimental data. There are differences among the various theoretical predictions on B* decays and future experimental data should help to discriminate among the various predictions.

Using the calculated values of the strong coupling constants of the heavy sextet spin-3/2 baryons to sextet and antitriplet heavy spin-1/2 baryons with light vector mesons within the light cone QCD sum rules method, and vector meson dominance assumption, the radiative decay widths are calculated. These widths are compared with the "direct" radiative decay widths predicted in the framework of the light cone QCD sum rules.
