Abstract

We report evidence for B0→D+D- and the first observation of the decay modes B-→D0D- and B-→D0D*- based on a sample of 152×106 BB̄ events collected by the Belle detector at KEKB. The branching fractions for B0→D+D-, B-→D0D-, and B-→D0D*- are found to be (1.91±0.51±0.30)×10-4, (4.83±0.78±0.58) ×10-4, and (4.57±0.71±0.56)×10-4, respectively. Charge asymmetries in the B-→D0D- and B-→D0D*- channels are consistent with zero.
