We present updated measurements of CP-violating asymmetries in the decays B0→D*±D and B0→D+D- using (383±4) ×106BB̄ pairs collected by the BABAR detector at the SLAC PEP-II B factory. We determine the time-integrated CP asymmetry AD*±D=0. 12±0.06±0.02, and the time-dependent asymmetry parameters to be CD*+D-=0.18±0.15±0.04, SD*+D-=-0.79±0. 21±0.06, CD*-D+=0.23±0.15±0.04, SD*-D+=-0. 44±0.22±0.06, CD+D-=0.11±0.22±0.07, and SD+D-=-0.54±0.34±0.06, where the first uncertainty is statistical and the second is systematic.

Abstract

We present updated measurements of CP-violating asymmetries in the decays B0→D*±D and B0→D+D- using (383±4) ×106BB̄ pairs collected by the BABAR detector at the SLAC PEP-II B factory. We determine the time-integrated CP asymmetry AD*±D=0. 12±0.06±0.02, and the time-dependent asymmetry parameters to be CD*+D-=0.18±0.15±0.04, SD*+D-=-0.79±0. 21±0.06, CD*-D+=0.23±0.15±0.04, SD*-D+=-0. 44±0.22±0.06, CD+D-=0.11±0.22±0.07, and SD+D-=-0.54±0.34±0.06, where the first uncertainty is statistical and the second is systematic.
