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±0.112 for the inclusive decay Bs0→Ds(*)+Ds(*)-, where the uncertainties are statistical and systematic. These results are the most precise single measurements to date and provide important constraints for indirect searches for nonstandard model physics in Bs0 mixing. © 2012 American Physical Society.
