Abstract

We report an improved measurement of the B+ → D+ ̄D0 and B0 → D0 ̄D0 decays based on 656.7 × 106 B ̄B events collected with the Belle detector at KEKB. We measure the branching fraction and charge asymmetry for the B+ → D+ ̄D0 decay: B(B+ → D+ ̄D0) = (3.85±0.31±0.38) × 10-4 and ACP (B+ → D+ ̄D0) = 0.00±0. 08±0.02, where the first error is statistical and the second is systematical. We also set the upper limit for the B0 → ̄D 0D0 decay: B(B0 → ̄D0D0) < 0.42×10-4 at 90% CL.
