Measurement of B-s(0) -> D-s(()*D-)+(s)(*()-) Branching Ratios

Abstract:

The decays Bs0→Ds(*)+Ds(*)- are reconstructed in a data sample corresponding to an integrated luminosity of 6.8fb -1 collected by the CDF II detector at the Tevatron pp̄ collider. All decay modes are observed with a significance of more than 10σ, 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±0.021±0.017 for Bs0→Ds+Ds-, 0.424±0. 046±0.035 for Bs0→Ds*±Ds, 0.654±0.072±0. 065 for Bs0→Ds*+Ds*-, and 1.261±0.095...
