Abstract
We present a first measurement of CP asymmetries in neutral B decays to D+D-, and updated CP asymmetry measurements in decays to D*D-+(-) and D*D--(+). We use fully reconstructed decays collected in a data sample of (232 +/- 3) x 10(6) Y (4S) -> BB B events in the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We determine the time-dependent asymmetry parameters to be SD*+D- = -0.54 +/- 0.35 +/- 0.07, CD*+D- = 0.09 +/- 0.25 +/- 0.06, SD*-D+ = -0.29 +/- 0.33 +/- 0.07, CD*-D+ = 0.17 +/- 0.24 +/- 0.04, SD+D- = -0.29 +/- 0.63 +/- 0.06, and CD+D- = 0.11 +/- 0.35 +/- 0.06, where in each case the first error is statistical and the second error is systematic.
