Radiative $B^{*} o B\gamma$ and $D^{*} o D\gamma$ decays in light cone QCD sum rules

摘要

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