| This dissertation presents the measurement of the the CP-odd fraction and time-dependent CP violation parameters for the B0 → D*+ D*- decay. These results are based on the full BABAR dataset of (467 +/- 5) x 106 BB¯ pairs collected at the PEP-II B Factory at the Stanford Linear Accelerator Center. An angular analysis finds that the CP-odd fraction of the B0 → D*+D*- decay is R⊥ = 0.158 +/- 0.028 +/- 0.006, where the first uncertainty is statistical, and the second is systematic. A fit to the flavor-tagged, time-dependent, angular decay rate yields C+=0.02+/-0.12+/-0.02 C⊥=0.41+/-0.50+/-0.08 S+=-0.76+/- 0.16+/-0.04 S⊥=-1.81+/- 0.71+/-0.16, for the CP-odd (⊥) and CP-even (+) contributions. Constraining these two contributions to be the same results in C=0.047+/-0.091+/-0.019 S=-0.71+/-0.16+/- 0.03. These measurements are consistent with the Standard Model and with measurements of sin2beta from B0 → (cc¯)K0 decays. |
