Abstract: | We present updated measurements of C P -violating asymmetries in the decays B 0 → D * ± D ∓ and B 0 → D + D − using ( 383 ± 4 ) × 10 6 B ¯¯¯ B pairs collected by the BABAR detector at the SLAC PEP-II B factory. We determine the time-integrated C P asymmetry A D * ± D ∓ = 0.12 ± 0.06 ± 0.02 , and the time-dependent asymmetry parameters to be C D * + D − = 0.18 ± 0.15 ± 0.04 , S D * + D − = − 0.79 ± 0.21 ± 0.06 , C D * − D + = 0.23 ± 0.15 ± 0.04 , S D * − D + = − 0.44 ± 0.22 ± 0.06 , C D + D − = 0.11 ± 0.22 ± 0.07 , and S D + D − = − 0.54 ± 0.34 ± 0.06 , where the first uncertainty is statistical and the second is systematic. |
