The radiative decays $B_c^{*\pm} \to B_c^{\pm} γ$ with QCD sum
rules

Zhi-Gang Wang
In this article, we calculate the $B_c^* \to B_c$ electromagnetic form-factor with the three-point QCD sum rules, then study the radiative decays $ B_c^{*\pm} \to B_c^{\pm} \gamma$. Experimentally, we can study the radiative transitions using the decay cascades $B_c^{*\pm}\to B_c^{\pm} \gamma\to J/\psi \ell^{\pm}\bar{\nu}_{\ell} \gamma\to \mu^+ \mu^- \ell^{\pm}\bar{\nu}_{\ell} \gamma$ in the future at the LHCb.
