First observation of B̄s0→Ds±K and Measurement of the Ratio of Branching Fractions B(B̄s0→Ds±K)/ B(B̄s0→Ds+π-)

First observation of B̄s0→Ds±K and Measurement of the Ratio of Branching Fractions B(B̄s0→Ds±K)/ B(B̄s0→Ds+π-)

A combined mass and particle identification fit is used to make the first observation of the decay B̄s0→Ds±K□ and measure the branching fraction of B̄s0→Ds±K□ relative to B̄s0→Ds+π-. This analysis uses 1.2fb-1 integrated luminosity of pp̄ collisions at s=1.96TeV collected with the CDF II detector at...
