Search for Inclusive b -> s lepton+ lepton-
We have searched for the effective FCNC decays b {yields} sl{sup +}l{sup -} using an inclusive method. We set upper limits on the branching ratios {Beta}(b {yields} se{sup +}e{sup -}) < 5.7 x 10{sup -5}, {Beta}(b {yields} s{mu}{sup +}{mu}{sup -}) < 5.8 x 10{sup -5}, and {Beta}(b {yields} se{sup {+-}}{mu}{sup {-+}}) < 2.2 x 10{sup -5} (at 90 % C.L.). Combining the di-electron and di-muon decay modes we find: {Beta}(b {yields} sl{sup +}l{sup -}) < 4.2 x 10{sup -5} (at 90 % C.L.).
