| Summary: | The decays B[subscript s][superscript 0]→D[subscript s](*)[superscript +]Ds(*)[superscript -] are reconstructed in a data sample corresponding to an integrated luminosity of 6.8 fb[superscript -1] collected by the CDF II detector at the Tevatron pp̅ collider. All decay modes are observed with a significance of more than 10σ, and we measure the B[subscript s][superscript 0] production rate times B[subscript s][superscript 0]→D[subscript s](*)[superscript +]D[subscript s](*)[superscript -] branching ratios relative to the normalization mode B[superscript 0]→D[subscript s][superscript +]D[superscript -]to be 0.183±0.021±0.017 for B[subscript s][superscript 0]→D[subscript s][superscript +]D[subscript s][superscript -], 0.424±0.046±0.035 for B[subscript s][superscript 0]→D[subscript s][superscript *]±D[subscript s][superscript ±], 0.654±0.072±0.065 for B[subscript s][superscript 0]→D[subscript s][superscript *+]D[subscript s][superscript *-], and 1.261±0.095±0.112 for the inclusive decay B[subscript s][superscript 0]→D[subscript s](*)[superscript +]Ds(*)[superscript -], 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 B[subscript s][superscript 0] mixing. |
