We report the results of a CP violation analysis of the decay B{sup {+-}} → D{sub??−?°}K{sup {+-}}, where D{sub?+?−?°} indicates a neutral D meson detected in the final state?+?−?°, excluding K{sub S}°?°. The analysis makes use of 324 million e+e− → B{bar B} events recorded by the BABAR experiment at the PEP-II e+e− storage ring. By analyzing the?+?−?° Dalitz plot distribution and the B{sup {+-}} → D{sub?+?−?°} K{sup {+-}} branching fraction and decay rate asymmetry, we calculate parameters related to the phase? of the CKM unitarity triangle. We also measure the magnitudes and phases of the components of the D° → {pi}+{pi}−{pi}° decay amplitude.

The authors present a preliminary measurement of CP-violation parameters in the decay B{sup 0} {yields} K{sup +}K{sup -}K{sup 0}, using approximately 347 million B{bar B} events collected by the BABAR detector at SLAC. Reconstructing the neutral kaon as K{sub S}{sup 0} {yields} {pi}{sup +}{pi}{sup -}, K{sub S}{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}, or K{sub L}{sup 0}, they analyze the Dalitz plot distribution and measure fractions to intermediate states. They extract CP parameters from the asymmetries in amplitudes and phases between B{sup 0} and {bar B}{sup 0} decays across the Dalitz plot. For decays to {phi}K{sup 0}, they find {beta}{sub eff} = 0.06 {+-} 0.16 {+-} 0.05, A{sub CP} = -0.18 {+-} 0.20 {+-} 0.10, where the first uncertainty is statistical and the second one is systematic. For decays to f{sub 0}K{sup 0}, they find {beta}{sub eff} = 0.18 {+-} 0.19 {+-} 0.04, A{sub CP} = 0.45 {+-} 0.28 {+-} 0.10. Combining all K{sup +}K{sup -}K{sup 0} events and taking account of the different CP eigenvalues of the individual Dalitz plot components, they find {beta}{sub eff} = 0.361 {+-} 0.079 {+-} 0.037, A{sub CP} = -0.034 {+-} 0.079 {+-} 0.025. The trigonometric reflection at {pi}/2 - {beta}{sub eff} is disfavored at 4.6{sigma}. They also study angular distributions in B{sup 0} {yields} K{sup +}K{sup -}K{sub S}{sup 0} and B{sup +} {yields} {phi}K{sup +} decays and measure the direct CP asymmetry in B{sup +} {yields} {phi}K{sup +} decays, A{sub CP} = 0.046 {+-} 0.046 {+-} 0.017.

We report a measurement of CP-violating asymmetries in B° → (??)° →??−?° decays using a time-dependent Dalitz plot analysis. The results are obtained from a data sample of 375 million?(4S) → B{bar B} decays, collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure 26 coefficients of the bilinear form-factor terms occurring in the time-dependent decay rate of the B° meson. We derive the physically relevant quantities from these coefficients. In particular, we measure a constraint on the angle? of the Unitarity Triangle.

I present measurements of the relative branching ratios, Dalitz plot structures and CP-asymmetry values in the three-body singly Cabibbo-suppressed decays D0 ->pi-pi+pi0 and D0 ->K-K+pi0 using data collected by the BaBar detector at the PEP-II asymmetric-energy ring at SLAC. I apply the results of the D0 ->pi-pi+pi0 analysis to extracting CP-violation parameters related to the CKM angle gamma (or phi_3) using the decay B- -> D0[->pi-pi+pi0] K-

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.

We constrain the apex of the Cabibbo-Kobayashi-Maskawa unitarity triangle with measurements of B-> K*pi amplitudes from analyses of B0-> K+pi-pi0 and B0-> K_Spi+pi- decays. This constraint is consistent with the world average. The B0-> K+pi-pi0 decay mode is reconstructed from a sample of 454 million B0B0bar events collected by the BABAR detector at SLAC. We measure direct CP violation in B0-> K*+pi- decays at the level of 3 sigma when measurements from both B0-> K+pi-pi0 and B0-> K_Spi+pi- decays are combined.

We constrain the apex of the Cabibbo-Kobayashi-Maskawa unitarity triangle with measurements of B → K*[pi] amplitudes from analyses of B0 → K+[pi]-[pi]0 and B0 → KS[pi]+[pi]- decays. This constraint is consistent with the world average. The B0 → K+[pi]-[pi]0 decay mode is reconstructed from a sample of 454 million B0$\bar{B}$ 0 events collected by the BABAR detector at SLAC. We measure direct CP violation in B0 → K*+[pi]- decays at the level of 3[sigma] when measurements from both B0 → K+[pi]-[pi]0 and B0 → KS[pi]+[pi]- decays are combined.

Particle physicists study the smallest particles and most basic rules of their interactions in humankind's current scope. The Charm Analysis Working Group (CWG) of the BaBar Collaboration studies decays involving the charm quark. They currently study mixing in D decays, an interesting and poorly understood phenomenon in current physics models. We, as part of the CWG, investigated the plausibility of using Dalitz plots and the BaBar analysis framework to study mixing in Wrong Sign (WS) D[sup 0][yields] K[pi][pi][sup 0] decays. Others in the CWG have studied mixing in the 2-body decay, D[sup 0][yields] K[pi]. The 3-body decay analyzed with the RooFitDalitz analysis package and Dalitz plots provides more information and another way of separating Doubly Cabibbo Suppressed Decays (DCSD) from mixing--which share the same end products. Through doing many simulations, we have demonstrated the usefulness of this approach. We selected D[sup 0][yields] K[pi][pi][sup 0] events from Simulation Production run No. 4 (SP4) and BaBar's run 1 and run 2. We made Dalitz plots with this data. Now that we better understand Dalitz plots and software, we plan to select WS D[sup 0][yields] K[pi][pi][sup 0] events and perform rate fits as discussed in BaBar Analysis Document (BAD) No. 443, as well as fits for several different decay times and resonances, in order to further distinguish DCSD from mixing.

The authors present preliminary results of improved measurements of the CP-violating asymmetries and branching fractions in the decays B° →??−, B° → K+?−, B° →?°?°, and B° → K°?°. This update includes all data taken at the?(4S) resonance by the BABAR experiment at the asymmetric PEP-II B-meson factory at SLAC, corresponding to 467 ± 5 million B{bar B} pairs. They find S{sub??} = -0.68 ± 0.10 ± 0.03, C{sub??} = -0.25 ± 0.08 ± 0.02,?{sub K{sub?}} = -0.107 ± 0.016{sub -0.004}, {sup +0.006}, C{sub?°?°} = -0.43 ± 0.26 ± 0.05,?(B° →?°?°) = (1.83 ± 0.21 ± 0.13) x 10−6,?(B° → K°?°) = (10.1 ± 0.6 ± 0.4) x 10−6, where the first error is statistical and the second is systematic. They observe CP violation with a significance of 6.7? in B° → {pi}− and 6.1? in B° → K+{pi}−. Constraints on the Unitarity Triangle angle? are determined from the isospin relation between all B → {pi}{pi} rates and asymmetries.
