B⁰_s Decays at Belle

The large data sample recorded with the Belle detector at the Υ(5S) energy provides a unique opportunity to study the poorly-known B⁰_s meson. Several analyses, made with a data sample representing an integrated luminosity of 23.6 fb⁻¹, are presented. We report the study of the large-signal B⁰_s → D^(*)−_s h⁺ (h⁺ = π⁺, ρ⁺) decays. In addition, several results on B⁰_s decays related to CP-violation studies are described. Beside the non-flavor specific decay, the following CP-eigenstate decays are studied: B⁰_s → J/ψη^('), B⁰_s → J/ψ f₀(980), the charmless B⁰_s → h (h = π⁺, K⁺, K⁰_S) and the three B⁰_s → D^(*)+_sD^(*)−_s modes from which ΔΓ^CP_s/Γ_s is extracted.
