Book excerpt: The decays B{sub s}° → D{sub s}{sup (*)+}D{sub s}{sup (*)-}s 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?, and we measure the B{sub s}° production rate times B{sub s}° → D{sub s}{sup (*)+} D{sub s}{sup (*)-} branching ratios relative to the normalization mode B° → D{sub s}d− to be 0.183 ± 0.021 ± 0.017 for B{sub s}° → D{sub s}+D{sub s}−, 0.424 ± 0.046 ± 0.035 for B{sub s}° → D{sub s}{sup ±} D{sub s}{sup {-+}}, 0.654 ± 0.072 ± 0.065 for B{sub s}° → D{sub s}{sup *+} D{sub s}{sup *-}, and 1.261 ± 0.095 {+-} 0.112 for the inclusive decay B{sub s}° → D{sub s}{sup (*)+}D{sub s}{sup (*)-}, 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 non-standard model physics in B{sub s}° mixing.
