Rare B → ννγ decay in light cone QCD sum rule

Using the light cone QCD Sum Rules Method, we study the rare B → ννγ decay and find that the branching ratios are, B(Bs → ννγ) ⋍ 7.5 × 10−8, B(Bd → ννγ) ⋍ 4.2 × 10−9. A comparison of our results on branching ratio with constituent quark and pole dominance model predictions are presented.
