B0s 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 B0s 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 B0s → D(*)-s h+ (h+ = π+, ρ+) decays. In addition, several results on B0s decays related to CP-violation studies are described. Beside the non-flavor specific decay, the following CP-eigenstate decays are studied: B0s → J/ψη('), B0s → J/ψ f0(980), the charmless B0s → h h-bar (h = π+, K+, K0S) and the three B0s → D(*)+sD(*)-s modes from which ΔΓCPs/Γs is extracted.
