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.).
