While the measurement of sin2[beta] is now a precision measurement, the constraints on the other two angles of the Unitarity Triangle, [alpha] and [gamma], are still limited by statistics and/or by theoretical uncertainties. This paper reports on the measurement of CP-violating asymmetries in B[sup 0] --> D(*)[sup [+-]][pi][sub [-+]] and B[sup 0] --> D[sup [+-]][rho][sup [-+]] decays in [Upsilon](4S) --> B[bar B] decays, asymmetries which are rleated to sin(2[beta] + [gamma]). This analysis updates the results already published by including a new decay mode (B[sup 0] --> D[sup [+-]][rho][sup [-+]]) and a larger data sample (110 instead of 88 million [Upsilon](4S) --> B[bar B] decays).

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 thesis reports on the final measurement of the flavor-mixing phase in decays of strange-bottom mesons (B_s) into J/psi and phi mesons performed in high-energy proton-antiproton collisions recorded by the Collider Experiment at Fermilab. Interference occurs between direct decays and decays following virtual particle-antiparticle transitions (B_s-antiB_s). The phase difference between transition amplitudes (“mixing phase”) is observable and extremely sensitive to contributions from non-standard-model particles or interactions that may be very hard to detect otherwise – a fact that makes the precise measurement of the B_s mixing phase one of the most important goals of particle physics. The results presented include a precise determination of the mixing phase and a suite of other important supplementary results. All measurements are among the most precise available from a single experiment and provide significantly improved constraints on the phenomenology of new particles and interactions.

The authors present updated measurements of time-dependent CP asymmetries in fully-reconstructed neutral B decays to several CP eigenstates containing a charmonium meson. The measurements use a data sample of (383 ± 4) x 106 [Upsilon](4S) → B{bar B} decays collected with the BABAR detector at the PEP-II B factory. They determine sin2[beta] = 0.714 ± 0.032(stat) ± 0.018(syst) and.

Furthermore, we present the results on the time-dependent CP asymmetry in neutral B meson decays to the CP eigenstate J/psiKL. The measurements use a data sample of about 88 million Upsilon(4S) & rarr; BB & d1; decays collected between 1999 and 2002 with the BABAR detector. We study events in which one neutral B meson is fully reconstructed in the J/psiKL final state and the other B meson is determined to be either a B0 or a B & d1;0 from its decay products. The amplitude of the CP asymmetry, which in the Standard Model is proportional to sin 2beta, is derived from the decay-time distributions in such events. We measure sin 2beta = 0.723 +/- 0.158(stat.)+/-0.086(syst.), which is consistent with Standard Model expectations.
