Abstract

We have searched for the effective flavor changing neutral-current decays b → sl⁺l^- using an inclusive method. We set upper limits on the branching ratios B(b → se⁺e^-) < 5.7 × 10^-5, B(b → sμ⁺μ^-) < 5.8 × 10^-5, and B(b → se^±μ^±) < 2.2 × 10^-5 [at 90% confidence level (C.L.)]. Combing the dielectron and dimuon decay modes we find B(b → sl⁺l^-) < 4.2 × 10^-5 (at 90% C.L.).
