Using a sample of 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BABAR detector at the PEP-II B Factory in 1999-2004, they study B{sup -} {yields} K{sup 0}K*(892){sup -} decays where K*{sup -} {yields} K{sub S}{sup 0} {pi}{sup -} and D{sup 0} {yields} K{sup -}{pi}{sup +}, K{sup -}{pi}{sup +}{pi}{sup 0}, K{sup -}{pi}{sup +}{pi}{sup +}{pi}{sup -} (non-CP final states); K{sup +}K{sup -}, {pi}{sup +}{pi}{sup -} (CP+ eigenstates); K{sub S}{sup 0}{pi}{sup 0}, K{sub S}{sup 0}{phi} and K{sub S}{sup 0}{omega} (CP- eigenstates). They measure four observables that are sensitive to the angle {gamma} of the CKM unitarity triangle; the partial-rate charge asymmetries A{sub CP{+-}} and the ratios of the B-decay branching fraction in CP{+-} and non-CP decays R{sub CP{+-}}: A{sub CP+} = -0.08 {+-} 0.19 (stat.) {+-} 0.08 (syst.); A{sub CP-} = -0.26 {+-} 0.40 (stat.) {+-} 0.12 (syst.); R{sub CP+} = 1.96 {+-} 0.40 (stat.) {+-} 0.11 (syst.); R{sub CP-} = 0.65 {+-} 0.26 (stat.) {+-} 0.08 (syst.).

The authors present preliminary observations of the decays of charged B mesons to a K* and a D[sup 0] where the latter particle is seen in final states of even and odd CP. They express the results in terms of R[sub CP] and A[sub CP]. With more statistics, these quantities will constrain [tau][sub B], the ratio of amplitudes defined in equations provided and the angle [gamma] of the unitary triangle by application of the Gronau-London-Wyler method.

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 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.

We present a study of the decay B− 2!D{sub (CP)}° K− and its charge conjugate, where D{sub (CP)}° is reconstructed in CP-even, CP-odd, and non-CP flavor eigenstates, based on a sample of 232 million [Upsilon](4S) 2!B{bar B} decays collected with the BABAR detector at the PEP-II ee− storage ring. We measure the partial-rate charge asymmetries AC{sub CP±} and the ratios R{sub CP±} of the B 2!D° K decay branching fractions as measured in CP± and non-CP D° decays: A{sub CP+} = 0.35 ± 0.13(stat) ± 0.04(syst), A{sub CP-} = -0.06 ± 0.13(stat) ± 0.04(syst), R{sub CP+} = 0.90 ± 0.12(stat) ± 0.04(syst), R{sub CP-} = 0.86 {+-} 0.10(stat) {+-} 0.05(syst).
