This thesis describes a high-quality, high-precision method for the data analysis of an interesting elementary particle reaction. The data was collected at the Japanese B-meson factory KEKB with the Belle detector, one of the most successful large-scale experiments worldwide. CP violation is a subtle quantum effect that makes the world look different when simultaneously left and right and matter and antimatter are exchanged. This being a prerequisite for our own world to have developed from the big bang, there are only a few experimental indications of such effects, and their detection requires very intricate techniques. The discovery of CP violation in B meson decays garnered Kobayashi and Maskawa, who had predicted these findings as early as 1973, the 2008 Nobel prize in physics. This thesis describes in great detail what are by far the best measurements of branching ratios and CP violation parameters in two special reactions with two charm mesons in the final state. It presents an in-depth but accessible overview of the theory, phenomenology, experimental setup, data collection, Monte Carlo simulations, (blind) statistical data analysis, and systematic uncertainty studies.

This book offers the first strong evidence of the existence of CP violation in neutral B decays extracted from sophisticated B factories in the US and Japan. It also holds out the expectation of rare B decays and D, K physics in the near future. In addition, new physics beyond the Standard Model is described. Both experimental and theoretical points of view are given.

We present a measurement of time-dependent CP asymmetries and an updated determination of the CP-odd fraction in the decay B[sup 0][yields] D*[sup+]D*[sup -] using a data sample of 88 x 10[sup 6] B[bar B] pairs collected by the BABAR detector at the PEP-II B Factory at SLAC. We determine the CP-odd fraction to be 0.063[+-] 0.055(stat)[+-] 0.009(syst). The time-dependent CP asymmetry parameters Im([lambda][sub+]) and[lambda][sub+] are determined to be 0.05[+-] 0.29(stat)[+-] 0.10(syst) and 0.75[+-] 0.19(stat)[+-] 0.02(syst), respectively. The Standard Model predicts these parameters to be -sin2[beta] and 1, respectively, in the absence of penguin diagram contributions.

This dissertation presents the measurement of 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 B$ar{B}$ 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 Rperpendicular = 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; Cperpendicular = 0.41 ± 0.50 ± 0.08; S+ = -0.76 ± 0.16 ± 0.04; S perpendicular = -1.81 ± 0.71 ± 0.16, for the CP-odd (perpendicular) and CP-even (plus) 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 sin2? from B0 → (c$ar{c}$)K0 decays.
