Measurement of the Ratios of Branching Fractions B(Bs0→Ds-π+)/B(B0→D-π+) and B(B+→D¯0π+)/B(B0→D-π+)
Abstract
We report an observation of the decay Bs0→Ds-π+ in pp¯ 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 pp¯ 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+→D¯0π+)/B(B0→D-π+)=1.97±0.10(stat)±0.21(syst), which is consistent with previous measurements.
