We present a measurement of the time-dependent CP-violating (CPV) asymmetries in B° → K{sub s}°[pi]° decays based on 124 million [Upsilon](4S) → B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. In a sample containing 122 ± 16 signal decays, we obtain the magnitude of the direct CPV asymmetry C{sub K{sub S}°[pi]°} = 0.40 {sub -0.28}{sup +0.27} ± 0.09 and the magnitude of the CPV asymmetry in the interference between mixing and decay S{sub K{sub S}°[pi]°} = 0.48 {sub -0.47}{sup +0.38} ± 0.06 where the first error is statistical and the second systematic.

The authors present a preliminary measurement of the time-dependent CP asymmetry for the neutral B-meson decay into the CP = +1 final state K{sub S}{sup 0}{pi}{sup 0}{pi}{sup 0}, with K{sub S}{sup 0} {yields} {pi}{sup +}{pi}{sup -} and {pi}{sup 0} {yields} {gamma}{gamma}. They use a sample of approximately 227 million B-meson pairs recorded at the {Upsilon}(4S) resonance by the BABAR detector at the PEP-II B-Factory at SLAC. From a maximum likelihood fit they extract the mixing-induced CP-violation parameter S{sub K{sub S}{sup 0}{pi}{sup 0}{pi}{sup 0}} = 0.84 {+-} 0.71(stat) {+-} 0.08(syst) and the direct CP-violation parameter C{sub K{sub S}{sup 0}}{pi}{sup 0}{pi}{sup 0} = 0.27 {+-} 0.52(stat) {+-} 0.13(syst), where the first uncertainty is statistical and the second systematic.

We present a measurement of the time-dependent CP asymmetry for the neutral B-meson decay into the CP = +1 final state K{sub S}°?°?°, with K{sub S}° →??−. We use a sample of approximately 227 million B-meson pairs recorded at the?(4S) resonance with the BABAR detector at the PEP-II B-Factory at SLAC. From an unbinned maximum likelihood fit we extract the mixing-induced CP-violation parameter S = 0.72 ± 0.71 ± 0.08 and the direct CP-violation parameter C = 0.23 ± 0.52 ± 0.13, where the first uncertainty is statistical and the second systematic.

The authors have presented an updated preliminary measurement of the CP-violating asymmetries in B[sup 0] --> f[sub 0](980)( --> [pi][sup +][pi][sup -])K[sub s][sup 0] decays. Their results for S and C are consistent with the Standard Model. The hypothesis of no mixing-induced CP violation is excluded at the 2.3[sigma] level.

We measure the time-dependent CP asymmetry parameters in B° 2!KK−K° based on a data sample of approximately 227 million B-meson pairs recorded at the [Upsilon](4S) resonance with the BABAR detector at the PEP-II B-meson Factory at SLAC. We reconstruct two-body B° decays to [phi](1020)K{sub s}° and [phi](1020)K{sub L}°, and the three-body decay KK−K{sub s}° with [phi](1020)K{sub s}° excluded. For the B° 2![phi]K° decays, they measure sin 2[beta]{sub eff}([phi]K°) = +0.50 ± 0.25(stat){sub -0.04}{sup +0.07}(syst). The B° 2!K+K−K{sub s}° decays are dominated by K+K− S-wave, as determined from an angular analysis; they measure sin 2[beta]{sub eff} (K+K−K{sub s}°) = +0.55 ± 0.22(stat) ± 0.04(syst) ± 0.11(CP), where the last error is due to the uncertainty in the fraction of CP-even contributions to the decay amplitude. We find no evidence for direct CP violation.

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.

We report a measurement of CP-violating asymmetries in B{sup 0} {yields} ({rho}{pi}){sup 0} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0} decays using a time-dependent Dalitz plot analysis. The results are obtained from a data sample of 347 million {Upsilon}(4S) {yields} 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{sup 0} meson and derive the physically relevant quantities from these coefficients. In particular we find a three standard deviation evidence of direct CP-violation in the B{sup 0} {yields} {rho}{sup {+-}}{pi}{sup {-+}} decays, with systematic uncertainties included. We also achieve a constraint of the angle {alpha} of the Unitarity Triangle. All results presented are preliminary.

The authors present a preliminary measurement of CP-violation parameters in the decay B° → KK−K{sub S}°, using approximately 465 million B{bar B} events collected by the BABAR detector at SLAC. Reconstructing the neutral kaon as K{sub S}° →?+?− or K{sub S}° →?°?°, 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° and {bar B}° decays across the Dalitz plot. From a fit to the whole Dalitz plot, they measure?{sub eff} = 0.44 ± 0.07 ± 0.02, A{sub CP} = 0.03 ± 0.07 ± 0.02, where the first uncertainties are statistical and the second ones are systematic. For decays to?K{sub S}°, they measure?{sub eff} = 0.13 ± 0.13 ± 0.02, A{sub CP} = 0.14 ± 0.19 ± 0.02. For decays to f0K{sub S}°, they measure?{sub eff} = 0.15 ± 0.13 ± 0.03, A{sub CP} = 0.01 ± 0.26 ± 0.07. From a fit to the region of the Dalitz plot with m{sub K{sup +}K−}> 1.1 GeV/c2, they measure?{sub eff} = 0.52 ± 0.08 ± 0.03, A{sub CP} = 0.05 ± 0.09 ± 0.04.
