Measurement of B+ -> D+ D0bar branching fraction and charge asymmetry and search for B0 -> D0 D0bar

Abstract

We report an improved measurement of the B+ -> D+ D0bar and B0 -> D0 D0bar decays based on 656.7 106 BBar events collected with the Belle detector at KEKB. We measure the branching fraction and charge asymmetry for the B+ -> D+ D0bar decay: Br(B+ -> D+ D0bar)= (3.85 +- 0.31 +- 0.38) 10-4 and ACP(B+ -> D+ D0bar)=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 -> D0 D0bar decay: Br(B0 -> D0 D0bar) < 0.42 10-4 at 90% CL.
