Title: Measurement of the inclusive semileptonic branching fraction B(B⁰ s→X -l +ν l) at Belle

Abstract

We report a measurement of the inclusive semileptonic B0s branching fraction in a 121 fb⁻¹ data sample collected near the Υ(5S) resonance with the Belle detector at the KEKB asymmetric energy e⁺e⁻ collider. Events containing B⁰ (*) sB¯¯¯⁰ (*) s pairs are selected by reconstructing a tag side D⁺ s and identifying a signal side lepton l⁺ (l=e, μ) that is required to have the same-sign charge to ensure that both originate from different B⁰ s mesons. The B⁰ s→X⁻l⁺ν l branching fraction is extracted from the ratio of the measured yields of D⁺ s mesons and D⁺ sl⁺ pairs and the known production and branching fractions. The inclusive semileptonic branching fraction is measured to be [10.6±0.5(stat)±0.7(syst)]%.
