Search for Inclusive b→ sl+]l⁻

Original · EN

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