Alternative Approach to $B^{-}\to {\eta }^{\prime }{K}^{-}$ Branching Ratio Calculation

Marina-Aura Dariescu, Ciprian Dariescu

Since the calculation of $BR(B^{-}\to {\eta }^{\prime }{K}^{-})$ in the framework of QCD improved factorization method, developed by Beneke et al., leads to numerical values much below the ex…
