摘要：
Inspired by the new measurements on B- -> eta((t))l (nu) over bar (l) from the BaBar Collaboration, we examine the constraint on the flavor-singlet mechanism, proposed to understand the large branching ratios for B -> eta'K decays. Based on the mechanism, we study the decays Of (B) over bar (d,s) -> eta((t))l(+)l(-) and find that they are sensitive to the flavor-singlet effects. In particular, we show that the decay branching ratios Of (B) over bar (d,s) -> eta'l(+)l(-) can be as large as O(10(-8)) and O(10(-6\)), respectively. (c) 2006 Elsevier B.V. All rights reserved.
