| dc.description | Inspired by the new measurements on $B^{-}\to η^{(\prime)}\ell \barν_{\ell}$ from the BaBar Collaboration, we examine the constraint on the flavor-singlet mechanism, proposed to understand the large branching ratios for $B\to η^{\prime} K$ decays. Based on the mechanism, we study the decays of $\bar B_{d,s}\to η^{(\prime)} \ell^{+} \ell^{-}$ and find that they are sensitive to the flavor-singlet effects. In particular, we show that the decay branching ratios of $\bar B_{d,s}\to η^{\prime} \ell^{+} \ell^{-}$ can be as large as $O(10^{-8})$ and $O(10^{-6})$, respectively. | |
