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 X 10^-5, B(b→ sμ⁺μ^-) < 5.8 X 10^-5 and Bb→se⁺μ^-) < 2.2 3 10^-5 [at 90% confidence level (C.L.)]. Combing the dielectron and dimuon decay modes we find b→sl⁺l^-) < 4.2 X 10^-5 (at 90% C.L.).
