The authors present measurements of the CP-violation parameters S and C for the radiative decays B° →?°K{sub S}°? and B° →?K{sub S}°?; for B →?K? they also measure the branching fractions and for B →?K+? the time-integrated charge asymmetry A{sub ch}. The data, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represent 467 x 106 B{bar B} pairs produced in e+e− annihilation at the PEP-II collider. In this summary they present an updated measurement of the time-dependent CP asymmetry in B° →?°K{sub S}°? decay mode and the first measurement of the time-dependent CP asymmetry in B° →?K{sub S}°? decay mode. Hadronic corrections in B° →?°K{sub S}°? decay mode might permit S to be as large as ± 0.1. Such corrections and NP effects could depend on m(?°K{sub S}°), so they split the data into two parts: the K*(892) region with 0.8

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.

This dissertation presents a measurement of the time-dependent CP-violating asymmetries in the neutral B-meson system performed with data collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The data sample used consists of 29.7 fb[sup -1] collected at the[Upsilon](4S) resonance and 3.9 fb[sup -1] collected off-resonance. We analyze three samples of fully-reconstructed B-meson decays: a sample of decays to CP eigenstates in the modes J/[psi] K[sub s][sup 0], [psi](2S) K[sub s][sup 0], [chi][sub cl] K[sub s][sup 0], and J/[psi] K*[sup 0] (822 events); as well as both charged (14304 events) and neutral (10457 events) B decays to flavor-eigenstates including D[sup (*)] and[pi]/[rho]/[alpha][sub 1]. In all cases, the proper decay time difference between the reconstructed B-meson and the recoiling B-meson is determined by measuring the separation of the two decay vertices. Furthermore, the flavor of the recoiling B-meson is tagged using a neural network algorithm. We use the flavor-eigenstate samples to calibrate both the vertexing and tagging performance. We measure the amplitude of the CP asymmetry, sin2[beta]= 0.61[+-] 0.14(stat)[+-] 0.06(syst). These results indicate the existence of indirect CP violation in the B-meson system.

We study the decay B− → DK*− using a sample of 379 x 106?(4S) → B{bar B} events collected with the BABAR detector at the PEP-II B-factory. We perform a 'GLW' analysis where the D meson decays into either a CP-even (CP+) eigenstate (KK−,?+?−), CP-odd (CP- ) eigenstate (K{sub S}°?°, K{sub S}°?, K{sub S}°?) or a non-CP state (K−?+). We also analyze D meson decays into K+?− from a Cabibbo-favored {bar D}° decay or doubly suppressed D° decay ('ADS' analysis). We measure observables that are sensitive to the CKM angle?: the partial-rate charge asymmetries A{sub CP±}, the ratios R{sub CP±} of the B-decay branching fractions in CP± and non-CP decay, the ratio R{sub ADS} of the charge-averaged branching fractions, and the charge asymmetry A{sub ADS} of the ADS decays: A{sub CP+} = 0.09 ± 0.13 ± 0.06, A{sub CP-} = -0.23 ± 0.21 ± 0.07, R{sub CP+} = 2.17 ± 0.35 ± 0.09, R{sub CP-} = 1.03 ± 0.27 ± 0.13, R{sub ADS} = 0.066 ± 0.031 ± 0.010, and A{sub ADS} = -0.34 {+-} 0.43 {+-} 0.16, where the first uncertainty is statistical and the second is systematic. Combining all the measurements and using a frequentist approach yields the magnitude of the ratio between the Cabibbo-suppressed and favored amplitudes, r{sub B} = 0.31 with a one (two) sigma confidence level interval of [0.24, 0.38] ([0.17, 0.43]). The value r{sub B} = 0 is excluded at the 3.3 sigma level. A similar analysis excludes values of? in the intervals [0, 7]{sup o}, [55, 111]{sup o}, and [175, 180]{sup o} ([85, 99]{sup o}) at the one (two) sigma confidence level.

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.
