Abstract

We have observed the decay B → D K , using 3.3 × 10 BB pairs collected with the CLEO II detector at the Cornell Electron Storage Ring. We find the ratio of branching fractions R ≡ B (B → D K )/B (B → D π ) = 0.055 ± 0.014 ± 0.005. © 1998 The American Physical Society. + ¯ 0 + 6 ¯ + ¯ 0 + + ¯ 0 +
