Abstract

Inspired by the new measurements on B- → η(′) ℓ over(ν, ̄) from the BaBar Collaboration, we examine the constraint on the flavor-singlet mechanism, proposed to understand the large branching ratios for B → η K decays. Based on the mechanism, we study the decays of over(B, ̄)d, s → η(′)+- and find that they are sensitive to the flavor-singlet effects. In particular, we show that the decay branching ratios of over(B, ̄)d, s → η+- can be as large as O (10-8) and O (10-6), respectively.
