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

The decays B-s(0) -> D-s((*))(+) D-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 (p) over bar collider. All decay modes are observed with a significance of more than 10 sigma, and we measure the B-s(0) production rate times B-s(0) -> D-s((*))(+) D-s((*))(-) branching ratios relative to the normalization mode B-0 -> D-s(+)D(-) to be 0.183 +/- 0.021 +/- 0.017 for B-s(0) -> D-s(+)D-s(-), 0.424 +/- 0.046 +/- 0.035 for B-s(0) -> D-s(*)(+/-)D-s(-/+), 0.654 +/- 0.072 +/- 0.065 for B-s(0) -> D-s(*)(+)D-s(*)(-), and 1.261 +/- 0.095 +/- 0.112 for the inclusive decay B-s(0) -> D-s((*))(+) D-s((*))(-), 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-s(0) mixing.
