This dissertation presents two analyses performed on data collected with the BABAR detector at the SLAC PEP-II e{sup +}e{sup -} asymmetric-energy B Factory. First, a Dalitz analysis is shown that performs the first measurement of CP violation parameters in the decay B{sup -} {yields} D{sub {pi}{sup +}{pi}{sup -}{pi}{sup 0}}K{sup -} using the decay rate asymmetry and D{sup 0} - {bar D}{sup 0} interference. The results can be used to further constrain the value of the CKM angle {gamma}. The second analysis studies the properties of the X(3872) in neutral and charged B {yields} J/{psi}{pi}{sup +}{pi}{sup -}K decays. Measurements of the branching ratio and mass are presented as well as the search for additional resonances at higher masses.

In this thesis we present the measurement of D0 - $\bar{D}$0 mixing parameter yCP using the full BABAR data sample. We also searched for CP violation in the D0 → K+K-, [pi]+[pi]- channels, finding the parameter [Delta]Y compatible with zero. In Chapter 1, we briefly review the SM and introduce the theoretical framework of neutral meson mixing and CP violation. The BABAR detector and the performance of each sub-detector are described in Chapter 2. In Chapter 3, we present an overview of the analysis including a brief description of the previous similar BABAR analyses and the expected improvements in the present analysis. The candidate reconstruction and selection are described in Chapter 4, together with the optimization of the signal region. The signal and background event classes are described in Chapter 5, where we also provide the probability density functions used to extract the mixing and CP violating parameter. In Chapter 6 we describe the various crosschecks performed to validate the analysis and the evaluation of the systematic error. Finally in Chapter 7 we present the final results and their interpretation.

We present results on time-dependent CP asymmetries in neutral B decays. The measurements use a data sample of about 88 million[Upsilon](4S)[yields] B[bar B] decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We study events in which one neutral B meson is fully reconstructed in a final state and the other B meson is determined to be either a B[sup 0] or[bar B][sup 0] from its decay products. Final states considered include B[sup 0][yields] J/[psi]K[sub S][sup 0], B[sup 0][yields] J/[psi]K[sub L][sup 0], B[sup 0][yields] J/[psi][pi][sup 0], B[sup 0][yields] D*[sup+] D*[sup -], B[sup 0][yields][phi]K[sub S][sup 0], B[sup 0][yields][pi][sup+][pi][sup -], and B[sup 0][yields][rho][sup[+-]][pi][sup[-+]].

The phenomenon of CP-violation in weak interactions, discovered in 1964 in decays of neutral kaons, receives a simple and elegant explanation in the Standard Model with three generations of quarks. Indeed, in this model the common source of CP-asymmetry phenomena is represented by a simple complex phase in the unitary matrix (the Cabibbo-Kobayashi-Maskawa matrix) describing the charged weak couplings of the quarks. This simple scheme has never received an accurate validation, because the phenomenological parameters determined from measurements of CP-violation in kaons decays are related to the fundamental parameters of the theory in a complex way, sensitive to large theoretical uncertainties. On the contrary, decays of neutral B mesons like B{sup 0} {yields} J/{psi} K{sub S}{sup 0} represent a unique laboratory to test the predictions of the theory because they are expected to show significant CP-violation effects, the magnitude of which is cleanly related to the Standard Model parameters. Thus experimental facilities have been built with the purpose of performing extensive studies of B decays. The BABAR experiment is operating at one of these facilities, at the Stanford Linear Accelerator Center. It is collecting data at the PEP-II asymmetric e{sup +}e{sup -} collider (E{sub e{sup -}} = 9.0 GeV; E{sub e{sup +}} = 3.1 GeV), a high-luminosity accelerator machine (L = 3 x 10{sup 33} cm{sup -2}s{sup -1}). The center-of-mass energy (10.58 GeV) of the e{sup +}e{sup -} system at PEP-II allows resonant production of the {Upsilon}(4S), a b{bar b} bound state, which decays almost exclusively in a B{sup 0}{bar B}{sup 0} or a B{sup +}B{sup -} pair. A high-acceptance detector, projected and built by a wide international collaboration, detects and characterizes the decay products of the B mesons. From the analysis of the data collected during the first two years of operation, the BABAR collaboration has established CP-violation in decays of neutral B mesons at the 4.1{sigma} level. Besides the primary goal of CP-violation studies, the high luminosity of PEP-II, coupled with the high acceptance of the BABAR detector, allows competitive studies of the properties of a wide set of B decay modes. In particular, measurements of non-leptonic decays are extremely useful to understand the dynamics of the non-perturbative strong interactions involved in these processes. In this thesis a study of the non-leptonic decay mode B{sup {+-}} {yields} J/{psi}{pi}{sup {+-}} is presented.
