Measurement of Bs0 --> Ds(*)+ Ds(*)- Branching Ratios

Abstract:

The decays Bs0 --> Ds(*)+ Ds(*)- are reconstructed in a data sample corresponding to an integrated luminosity of 6.8 fb-1 collected by the CDF II detector at the Tevatron p\bar{p} collider. All decay modes are observed with a significance of more than 10 sigma, and we measure the Bs0 production rate times Bs0 --> Ds(*)+ Ds(*)- branching ratios relative to the normalization mode B0 --> Ds+ D- to be $0.183 \pm 0.021 \pm 0.017$ for Bs0 --> Ds+ Ds-, $0.424 \pm 0.046 \pm 0.035$ for Bs0...
