First observation of the decay Bs0→Ds-Ds+ and measurement of its branching ratio
We report the observation of the exclusive decay Bs0→Ds-Ds+ at the 7.5 standard deviation level using 355pb-1 of data collected by the CDF II detector in pp̄ collisions at s=1.96TeV at the Fermilab Tevatron. We measure the relative branching ratio B(Bs0→Ds-Ds+)/B(B0→D-Ds+)=1.44-0.44+0.48. Using the...
