Abstract

We report a measurement of the inclusive semileptonic Bs0 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 Bs0(*) B̄s0(*) pairs are selected by reconstructing a tag side Ds+ 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 Bs0 mesons. The Bs0→X ^-ℓ⁺ν_ℓ branching fraction is extracted from the ratio of the measured yields of Ds+ mesons and Ds+ℓ⁺ 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)]%.

N2 - We report a measurement of the inclusive semileptonic Bs0 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 Bs0(*) B̄s0(*) pairs are selected by reconstructing a tag side Ds+ 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 Bs0 mesons. The Bs0→X -ℓ+νℓ branching fraction is extracted from the ratio of the measured yields of Ds+ mesons and Ds+ℓ+ 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)]%.
