Rare B -> Nu Barnu Gamma Decay in Light Cone QCD Sum Rule

الأصل · EN

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.
