Rare B -> Nu Barnu Gamma Decay in Light Cone QCD Sum Rule
Abstract
Using the light cone QCD Sum Rules Method, we study the rare B -> nu barnu gamma decay and and find that the branching ratios are, B(Bs -> nu barnu gamma) = 7.5 10-8, B(Bd -> nu -> nu gamma) = 4.2 10-9. A comparision of our results, on branching ratio, with constituent quark and pole dominance model predictions are presented.
