On the Role of Charm in Decay of B-mesons to η ′ K


In this letter we focus on the calculation of f (c) η ′ , the amplitude of the (c¯ c) → (gluons) → η ′ transition, which provides the magnitude of the contribution of the Cabbibo favored b → ¯ ccs elementary process to B → η ′ K decay. It is found that f (c) η ′ = −12.3 ∼ −18.4 M eV on the scale of m c. This number is in a strong contradiction with the… (More)
