摘要：

We present measurements of the branching fraction and CP-violating asymmetries for neutral B decays to D*+/-D-/+. The measurement uses a data sample of approximately 88x10(6) Y(4S)-->B (B) over bar decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)-e(-) collider. By fully reconstructing the D*+/-D-/+ decay products, we measure the branching fraction to be (8.8+/-1.0+/-1.3)x10(-4) and the time-integrated CP-violating asymmetry between the rates to D*-D+ and D*+D- to be A=-0.03+/-0.11+/-0.05. We also measure the time-dependent CP-violating asymmetry parameters to be S-+=-0.24+/-0.69+/-0.12, C-+=-0.22+/-0.37+/-0.10 for B-->D*-D+ and S+-=-0.82+/-0.75+/-0.14, C+-=-0.47+/-0.40+/-0.12 for B-->D*+D-. In each case, the first error is statistical and the second error is systematic.
