First Observation of B[over-bar][subscript s][superscript 0]-->D[subscript s][superscript ±]K[superscript ∓] and Measurement of the Ratio of Branching Fractions B(B[over-bar][subscript s][superscript 0]-->D[subscript s][superscript ±]K[superscript ∓]/B([over-bar][subscript s][superscript 0]-->D[subscript s][superscript +] pi[superscript -])

First Observation of B[over-bar][subscript s][superscript 0]-->D[subscript s][superscript ±]K[superscript ∓] and Measurement of the Ratio of Branching Fractions B(B[over-bar][subscript s][superscript 0]-->D[subscript s][superscript ±]K[superscript ∓]/B([over-bar][subscript s][superscript 0]-->D[subscript s][superscript +] pi[superscript -])

A combined mass and particle identification fit is used to make the first observation of the decay B[over-bar] s0-->Ds±K∓ and measure the branching fraction of B[over-bar] s0-->Ds±K∓ relative to B[over-bar] s0-->Ds+pi-. This analysis uses 1.2  fb-1 integrated luminosity of pp[over-bar]...
