Measurement of the semileptonic branching fraction of the B[subscript s] meson
We report a measurement of the inclusive semileptonic branching fraction of the B[subscript s] meson using data collected with the BABAR detector in the center-of-mass energy region above the Υ(4S) resonance. We use the inclusive yield of ϕ mesons and the ϕ yield in association with a high-momentum...

description | We report a measurement of the inclusive semileptonic branching fraction of the B[subscript s] meson using data collected with the BABAR detector in the center-of-mass energy region above the Υ(4S) resonance. We use the inclusive yield of ϕ mesons and the ϕ yield in association with a high-momentum lepton to perform a simultaneous measurement of the semileptonic branching fraction and the production rate of B[subscript s] mesons relative to all B mesons as a function of center-of-mass energy. The inclusive semileptonic branching fraction of the B[subscript s] meson is determined to be B(B[subscript s]-->ℓνX)=9.5-2.0+2.5(stat)-1.9+1.1(syst)%, where ℓ indicates the average of e and μ. |
