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.

Results of recent searches for new physics in CP violation in charm decays from the BABAR experiment are presented. These results include a measurement of D0 - anti D0 mixing and searches for CP violation in two-body D0 decays, a search for CP violation in the charm decays D" 2!KS0K " and D s" 2!KS0K", KS0[pi]", and a search for direct CP violation in the singly-Cabibbo suppressed D" 2!K+K-[pi]"decays. These studies are based on the fi nal dataset collected by BABAR at the PEP-II B factory at SLAC in the period 1999-2008. No evidence of CP violation is found in these charm decays. The measured mixing parameter yCP = [0.72 " 0.18(stat) " 0.12(syst)]% excludes the no-mixing null hypothesis with a signifi cance of 3.3[sigma].

The BABAR experiment at SLAC provides an opportunity for measurement of CP violation in B decays. A measurement of time-dependent CP violating asymmetries using exclusive B meson decays where the b quark decays to c{bar c}d (including B° 2!D*D*− and B° 2!D*{sup ±}D{sup {-+}} decays) is presented here. This is the first measurement of CP violation in a mode sensitive to the Unitarity Triangle parameter sin2[beta] outside of decays containing charmonium. It provides a comparison to measurements of sin2[beta] using b 2!c{bar c}s, and permits an observation into potential new physics sources of CP violation, such as supersymmetry, via differences between these measurements and those of B° 2!J/[psi] K{sub S}° as statistics of reconstructed neutral B decays to D{sup (*)+} D{sup (*)-} increase. The measured value of the time-dependent CP violating asymmetries are: S = 0.38 ± 0.88(stat) ± 0.12(syst) and C = -0.30 ± 0.50(stat) ± 0.13(syst) for B° 2!D*− D; S = -0.43 ± 1.41(stat) ± 0.23(syst) and C = 0.53 ± 0.74(stat) ± 0.15(syst) for B° 2!D*+ D−; and S = -0.05 ± 0.45(stat) ± 0.05(syst) and C = 0.12 ± 0.30(stat) {+-} 0.05(syst) for B° 2!D*− D+; where S corresponds to CP violation in the interference of mixing and decay and C corresponds to CP violation in decay.

The most recent results obtained by the BABAR experiment at the PEP-II asymmetric-energy B Factory at SLAC on CP-violating asymmetries and branching fractions for neutral and charged B decays are presented here. The analysis was performed on a data sample of[approx] 88 million[Upsilon](4S)[yields] B[bar B] decays collected between 1999 and 2002. Using b[yields] c[bar c]s decays, we measure sin2[beta]= 0.741[+-] 0.067(stat)[+-] 0.034(syst). We also present sin2[beta] measurements from, b[yields] s[bar s]s and b[yields] c[bar c]d processes. From neutral B meson decays to two-body final states of charged pions and kaons, we derive for the CP violating parameters, S[sub[pi][pi]]= 0.02[+-] 0.34[+-] 0.05[-0.54,+0.58] and C[sub[pi][pi]]= -0.30[+-] 0.25[+-] 0.04[-0.72,+0.12]. First results for B[yields][pi][sup+][pi][sup -][pi][sup 0] and K[sup[+-]][pi][sup[-+]][pi][sup 0] final states dominated by the[rho][sup[+-]] resonance, are also presented.

The authors present BABAR experiment studies to observe CP violation in the two-body decays ({pi}K and {pi}{pi}) and the quasi two-body decays ({rho}K and {rho}{pi}) of B mesons. The results are obtained from data samples of about 89(123) million {Upsilon}(4S) {yields} B{bar B} decays collected between 1999 and 2002(2003) with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.

Mixing and CP violation in charm meson decays provide a unique probe of possible physics beyond the standard model. In this paper, we give a brief review of the current measurements from the BABAR experiment.
