Observation of Cabibbo suppressed B → D(*)K- decays at Belle
By taking advantage of the good high momentum particle identification capability of Belle, signals were observed for the Cabibbo suppressed decays B → D0K-, D+K-, D*0K-, and D*+K-. Values for the ratios of branching fractions R = B (B → D(*)K-)/B(B → D(*)π-) showed good agreement, within errors, with naive model calculation.
