Abstract

We report observations of the Cabibbo suppressed decays B → D(*)K- using a 10.4fb^-1 data sample accumulated at the ϒ(4S) resonance with the Belle detector at the KEKB e⁺e_- storage ring. We find that the ratios of Cabibbo suppressed to Cabibbo favored branching fractions are B(B- → D⁰K-)/B(B- → D⁰π-) = 0.079 ± 0.009 ± 0.006, B(⊯ B⁰ → D⁺K-)/B(⊯B⁰ → D⁺π-) = 0.068 ± 0.015 ± 0.007, B(B- → D^*0K-)/B(B- → D^*0π-) = 0.078 ± 0.019 ± 0.009, and B(⊯ B⁰ → D^*+K-)/B(⊯B⁰ → D^*+π-) = 0.074 ± 0.015 ± 0.006. These are the first observations of the B → D⁺K-, D^*0K-, and D^*+K- decay processes.

These are the first observations of the B → D+K-, D*0K-, and D*+K- decay processes.

AB - We report observations of the Cabibbo suppressed decays B → D(*)K- using a 10.4fb-1 data sample accumulated at the ϒ(4S) resonance with the Belle detector at the KEKB e+e- storage ring. We find that the ratios of Cabibbo suppressed to Cabibbo favored branching fractions are B(B- → D0K-)/B(B- → D0π-) = 0.079 ± 0.009 ± 0.006, B(⊯ B0 → D+K-)/B(⊯B0 → D+π-) = 0.068 ± 0.015 ± 0.007, B(B- → D*0K-)/B(B- → D*0π-) = 0.078 ± 0.019 ± 0.009, and B(⊯ B0 → D*+K-)/B(⊯B0 → D*+π-) = 0.074 ± 0.015 ± 0.006. These are the first observations of the B → D+K-, D*0K-, and D*+K- decay processes.
