Abstract
We present a study of the decays B[superscript ±]→DK[superscript ±] with D mesons reconstructed in the K[superscript +]π[superscript -]π[superscript 0] or K[superscript -]π[superscript +]π[superscript 0] final states, where D indicates a D[superscript 0] or a D̅[superscript 0] meson. Using a sample of 474×10[superscript 6] BB̅ pairs collected with the BABAR detector at the PEP-II asymmetric-energy e[superscript +]e[superscript -] collider at SLAC, we measure the ratios R[superscript ±]≡Γ(B[superscript ±]→[K[superscript ∓]π[superscript ±π]0][subscript D]K[superscript ±])/Γ(B[superscript ±]→[K[superscript ±]π[superscript ∓]π[superscript 0]][subscript D]K[superscript ±]). We obtain R[superscript +]=(5[subscript -10][superscript +12](stat)-4[superscript +2](syst))×10[superscript -3] and R-=(12[subscript -10][[superscript +12](stat)[subscript -5][[superscript +3](syst))×10[superscript -3], from which we extract the upper limits at 90% probability: R[superscript +]<23×10[superscript -3] and R[superscript -]<29×10[superscript -3]. Using these measurements, we obtain an upper limit for the ratio r[subscript B] of the magnitudes of the b→u and b→c amplitudes r[subscript B]<0.13 at 90% probability.
