Abstract

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 -> Ds+D- to be 0.183 +/- 0.021 +/- 0.017 for B-s(0) -> Ds+Ds-, 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.
