摘要：
In this article, we calculate the B-c* -> B-c electromagnetic form-factor with the three-point QCD sum rules and then study the radiative decays B-c*(+/-) -> B-c(+/-)gamma. Experimentally, we can study the radiative transitions using the decay cascades B-c*(+/-) -> B-c(+/-)gamma -> J/psi l(+/-)(nu) over bar(l)gamma -> mu(+)mu(-)l(+/-)(nu) over bar(l)gamma. in the future at the LHCb.
