    Abstract:
    We report an observation of the decay Bs0→Ds-π+ in pp̄ collisions at s=1.96TeV using 115pb-1 of data collected by the CDF II detector at the Fermilab Tevatron. We observe 83±11(stat) Bs0→Ds-π+ candidates, representing a large increase in statistics over previous measurements and the first observation of this decay at a pp̄ collider. We present the first measurement of the relative branching fraction B(Bs0→Ds-π+)/B(B0→D-π+)=1.32±0.18(stat)±0.38(syst) . We also measure B(B+→D̄0π+)/B(B0→D-π+)=1.97±0. 10(stat)±0.21(syst), which is consistent with previous measurements. © 2006 The American Physical Society.
