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

preprint1995arXivOpen access

The radiative decays $B^{*} (D^{*})\to B(D) γ$ 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.
