The authors present a preliminary measurement of CP-violating parameters S and C from fits of the time-dependence of B° meson decays to [eta]'K°. The data were recorded with the BABAR detector at PEP-II and correspond to 227 x 106 B{bar B} pairs produced in ee− annihilation through the [Upsilon](4S) resonance. From a maximum likelihood fit they measure the CP-violation parameters S = 0.27 ± 0.14 (stat.) ± 0.03 (syst.) and C = -0.21 ± 0.10 (stat.) ± 0.03 (syst.).

The authors present updated measurements of time-dependent Cp asymmetries in fully reconstructed neutral B decays containing a charmonium meson. The measurements reported here use a data sample of (465 ± 5) x 106 [Upsilon](4S) 2!B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric energy ee− storage rings operating at the SLAC National Accelerator Laboratory. The time-dependent CP asymmetry parameters measured from J/[psi] K{sub S}°, J/[psi]K{sub L}°, [psi](2S)K{sub S}°, [eta]{sub c}K{sub S}°, [chi]{sub c1}K{sub S}° and J/[psi] K*(892)° decays are: C{sub f} = 0.024 ± 0.020(stat) ± 0.016(syst) and -[eta]{sub f}S{sub f} = 0.687 ± 0.028(stat) ± 0.012(syst).

In this thesis work we have measured the following upper limits at 90% of confidence level, for B meson decays (in units of 10-6), using a statistics of 465.0 x 106 B$ar{B}$ pairs: ?(B0 → ?K0) 1.6 ?(Bsup0/sup → ??) 1.4 ?(Bsup0/sup → ?'?') 2.1 ?(Bsup0/sup → ??) 0.52 ?(Bsup0/sup → ??) 1.6 ?(Bsup0/sup → ?'?) 1.2 ?(Bsup0/sup → ?'?) 1.7 We have no observation of any decay mode, statistical significance for our measurements is in the range 1.3-3.5 standard deviation. We have a 3.5? evidence for B → ?? and a 3.1 ? evidence for B → ?'?. The absence of observation of the Bsup0/sup → ?Ksup0/sup open an issue related to the large difference compared to the charged mode Bsup+/sup → ?Ksup+/sup branching fraction, which is measured to be 3.7 ± 0.4 ± 0.1 [118]. Our results represent substantial improvements of the previous ones [109, 110, 111] and are consistent with theoretical predictions. All these results were presented at Flavor Physics and CP Violation (FPCP) 2008 Conference, that took place in Taipei, Taiwan. They will be soon included into a paper to be submitted to Physical Review D. For time-dependent analysis, we have reconstructed 1820 ± 48 flavor-tagged Bsup0/sup → ?'Ksup0/sup events, using the final BABAR statistic of 467.4 x 10sup6/sup B$ar{B}$ pairs. We use these events to measure the time-dependent asymmetry parameters S and C. We find S = 0.59 ± 0.08 ± 0.02, and C = -0.06 ± 0.06 ± 0.02. A non-zero value of C would represent a directly CP non-conserving component in Bsup0/sup → ?'Ksup0

The authors report a measurement of the time-dependent CP-asymmetry parameters S and C in color-suppressed B° 2!D{sup (*)0}h° decays, where h° is a [pi]°, [eta], or [omega] meson, and the D° decays to one of the CP eigenstates KK−, K{sub S}°[pi]°, or K{sub S}°[omega]. The data sample consists of 383 x 106 [Upsilon](4S) 2!B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B-factory at SLAC. The results are S = -0.56 ± 0.23 ± 0.05 and C = -0.23 ± 0.16 ± 0.04, where the first error is statistical and the second is systematic.

The authors present a preliminary measurement of CP-violating parameters S and C from fits of the time-dependence of B{sup 0} meson decays to {eta}'K{sub L}{sup 0}. The data were recorded with the BABAR detector at PEP-II and correspond to 232 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation through the {Upsilon}(4S) resonance. By fitting the time-dependent CP asymmetry of the reconstructed B{sup 0} {yields} {eta}'K{sub L}{sup 0} events, they find S = 0.60 {+-} 0.31 {+-} 0.04 and C = 0.10 {+-} 0.21 {+-} 0.03, where the first error quoted is statistical and the second is systematic. They also perform a combined fit using both {eta}'K{sub S}{sup 0} and {eta}'K{sub L}{sup 0} data, and find S = 0.36 {+-} 0.13 {+-} 0.03 and C = -0.16 {+-} 0.09 {+-} 0.02.

The authors present a first measurement of CP asymmetries in neutral B decays to DD−, and updated CP asymmetry measurements in decays to D*D− and D*−D+. They use fully-reconstructed decays collected in a data sample of (232 ± 3) x 106 [Upsilon](4S) 2!B{bar B} events in the BABAR detector at the PEp-II asymmetric-energy B Factory at SLAC. they determine the time-dependent asymmetry parameters to be S{sub D*+D−} = -0.54 ± 0.35 ± 0.07, C{sub D*+D−} = 0.09 ± 0.25 ± 0.06, S{sub D*−D{sup +}} = -0.29 ± 0.33 ± 0.07, C{sub D*−D{sup +}} = 0.17 ± 0.24 ± 0.04, S{sub D{sup +}D{sup -}} = -0.29 ± 0.63 ± 0.06, and C{sub D{sup +}D{sup -}} = 0.11 ± 0.35 ± 0.06, where in each case the first error is statistical and the second error is systematic.
