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 --> s mu(+)mu(-)) < 5.8 x 10(-5), and B(b --> se(+/-)mu(-/+)) < 2.2 x 10(-5) [at 90% confidence level(C.L.)]. Combing the dielectron and dimuon decay modes we find B(b --> sl(+)l(-)) < 4.2 x 10(-5) (at 90% C.L.).
