Abstract

We report the observation of the exclusive decay Bs0DsDs+ at the 7.5 standard deviation level using 355pb1 of data collected by the CDF II detector in pp¯ collisions at s=1.96TeV at the Fermilab Tevatron. We measure the relative branching ratio B(Bs0DsDs+)/B(B0DDs+)=1.440.44+0.48. Using the world average value for B(B0DDs+), we find B(Bs0DsDs+)=(9.44.2+4.4)×103. This provides a lower bound ΔΓsCP/Γs2B(Bs0DsDs+)>1.2×102 at 95% C.L.
