Abstract

We present new measurements of time-dependent CP asymmetries for B-0 -> D-(*()+) D-(*()-) decays using (467 +/- 5) X 10(6) B (B) over bar pairs collected with the BABAR detector located at the PEP-II B Factory at the Stanford Linear Accelerator Center. We determine the CP-odd fraction of the B-0 -> D-(*()+) D-(*()-) decays to be R-perpendicular to = 0.158 +/- 0.028 +/- 0.006 and find CP asymmetry parameters S+ = -0.76 +/- 0.16 +/- 0.04 and C+ = +0.00 +/- 0.12 +/- 0.02 for the CP-even component of this decay and S-perpendicular to = -1.80 +/- 0.70 +/- 0.16 and C-perpendicular to = +0.41 +/- 0.49 +/- 0.08 for the CP-odd component. We measure S = -0.63 +/- 0.36 +/- 0.05 and C = -0.07 +/- 0.23 +/- 0.03 for B-0 -> D+D-, S = -0.62 +/- 0.21 +/- 0.03 and C = +0.08 +/- 0.17 +/- 0.04 for B-0 -> D*D-+(-), and S = -0.73 +/- 0.23 +/- 0.05 and C = +0.00 +/- 0.17 +/- 0.03 for B-0 -> D+D*(-). For the B-0 -> D*(+/-) D-+/- decays, we also determine the CP-violating asymmetry (A) over bar = +0.008 +/- 0.048 +/- 0.013. In each case, the first uncertainty is statistical and the second is systematic. The measured values for the asymmetries are all consistent with the standard model.
