Abstract

We present the first observation of the decay $$\bar{B}$$$0\atop{s}$$→ D$$±\atop{s}$$ K∓ and measure the relative branching fraction of $$\bar{B}$$$0\atop{s}$$ → D$$±\atop{s}$$ K∓ to $$\bar{B}$$$0\atop{s}$$ → D$$+\atop{s}$$ π ^-. The measurement of the relative branching fraction is performed by applying a fit in invariant mass and specific ionization to 1.2 fb ^-1 of D _s(φπ)X data collected with the CDF II detector in pp collisions at √ s = 1.96 TeV at the Fermilab Tevatron collider. We measure B $$\bar{B}$$$0\atop{s}$$ → D$$±\atop{s}$$ K∓ /B $$\bar{B}$$$0\atop{s}$$ → D$$+\atop{s}$$ π ^- = 0.107±0.019(stat)±0.008(sys). The statistical significance of the $$\bar{B}$$$0\atop{s}$$ → D$$±\atop{s}$$ K ^∓ signal is 7.9σ. To cross-check our analysis method, we also measure B $$\bar{B0}$$→ D ⁺K ^- /B $$\bar{B0}$$ → D ⁺π ^- and B $$\bar{B0}$$ → D ^+*K ^- /B $$\bar{B0}$$ → D ^*+π ^- and verify that our results are in agreement with the world average.
