Bs0 Decays at Belle

Abstract

The large data sample recorded with the Belle detector at the Υ(5S) energy provides a unique opportunity to study the poorly-known Bs meson. Several analyses, made with a data sample representing an integrated luminosity of 23.6 /fb, are presented. We report the study of the large-signal Bs {\to} Ds- h+ (h+ = π+, ρ+) decays. In addition, several results on Bs decays related to CP-violation studies are described. Beside the non-flavor specific Bs {\to} Ds K decay, the following CP-eigenstate decays are studied: Bs {\to} J/ψ η('), Bs {\to} J/ψ f0(980), the charmless Bs {\to} hh (h = π+, K+, KS0) and the three Bs {\to} Ds(*) Ds(*) modes from which ΔΓs(CP)/Γs is extracted.
