QCD sum rule analysis of the rare radiative B(c)-> D(s)*gamma decay

Azizi, K.
Bashiry, V.
In this work, the radiative B(c)-> D(s)(*)gamma decay is investigated in the framework of QCD sum rules. The transition form factors responsible for the decay are calculated. The total branching ratio for this decay is estimated to be in the order of 10(-5), so this decay can be measurable at LHC in the near future.
