Radiative $B^{*}Bγ$ and $D^{*}Dγ$ coupling constants in light cone QCD sum rules

The radiative decays $ B^{*} (D^{*})\to B(D) \gamma$ are investigated in the framework of light cone QCD sum rules. The transition amplitude and decay rates are estimated.It is shown that our results on branching ratios of D meson decays are in good agreement with the existing experimental data.
