We report a measurement of the inclusive semileptonic branching fraction of the B s meson using data collected with the BABAR detector in the center-of-mass energy region above the Υ(4S) resonance.

Abstract

We report a measurement of the inclusive semileptonic branching fraction of the B 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 mesons and the yield in association with a high-momentum lepton to perform a simultaneous measurement of the semileptonic branching fraction and the production rate of B s mesons relative to all B mesons as a function of center-of-mass energy. The inclusive semileptonic branching fraction of the B s meson is determined to be B(B s→νX)=9.5-2.0+2.5(stat)-1.9+1.1(syst)%, where indicates the average of e and μ.
