Abstract

We report an improved measurement of the B+→D+D̄0 and B0→D0D̄0 decays based on 657×106 BB̄ events collected with the Belle detector at KEKB. We measure the branching fraction and charge asymmetry for the B+→D+D̄0 decay: B(B+→D+D̄0)=(3. 85±0.31±0.38)×10-4 and ACP(B+→D+D̄0)=0. 00±0.08±0.02, where the first error is statistical and the second is systematic. We also set the upper limit for the B0→D0D̄0 decay: B(B0→D0D̄0)<0.43×10-4 at 90% CL.
