Measurement of the B→Xsl+l- branching fraction with a sum over exclusive modes -: art. no. 081802

We measure the branching fraction for the flavor-changing neutral-current process B-->X(s)l(+)l(-) with a sample of 89x10(6) Y(4S)-->B (B) over bar events recorded with the BABAR detector at the PEP-II e(+)e(-) storage ring. The final state is reconstructed from e(+)e(-) or mu(+)mu(-) pairs and a hadronic system X-s consisting of one K+/- or K-S(0) and up to two pions, with at most one pi(0). We observe a signal of 40+/-10(stat)+/-2(syst) events and extract the inclusive branching fraction B(B-->X(s)l(+)l(-))=(5.6+/-1.5(stat)+/-0.6(exp syst)+/-1.1(model syst))x10(-6) for m(l)(+)l(-)>0.2 GeV/c(2).
