The authors' main claim Combining the di-electron and di-muon decay modes we find: B(b->s l+l-) < 4.2 10^{-5} (at 90 % C.L.).
The compiled record
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

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.).

We integrate over a continuum region below the $ψ$ resonances to find the integrated ratio R_e^+e^-|_[1,6]≡∫_1GeV^2^6 GeV^2 R_e^+e^-(q^2)d q^2, which we can finally compare to the experimental result [ref] _e^+e^- |_[1,6] = (1.60±0.51) ·10^-6, also normalized to the semileptonic decay.
