Book Description
We present updated results on time-dependent CP asymmetries in fully reconstructed B° → D{sup (*)±}[pi]{sup {-+}} and B° → D{sup ±}[rho]{sup {-+}} decays in approximately 232 million [Upsilon](4S) → B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. From a time-dependent maximum likelihood fit we obtain for the parameters related to the CP violation angle 2[beta] + [gamma]: a{sup D{pi}} = -0.010 ± 0.023 ± 0.007, c{sub lep}{sup D{pi}} = -0.033 ± 0.042 ± 0.012, a{sup D*{pi}} = -0.040 ± 0.023 ± 0.010, C{sub lep}{sup D*{pi}} = 0.049 ± 0.042 ± 0.015, a{sup D{rho}} = -0.024 ± 0.031 ± 0.009, c{sub lep}{sup D{rho}} = -0.098 {+-} 0.055 {+-} 0.018, where the first error is statistical and the second is systematic. Using other measurements and theoretical assumptions, we interpret the results in terms of the angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle and find

Book Description
We present new measurements of time-dependent CP asymmetries for B° --> D{sup (*)+}d{sup (*)-} decays using (467 ± 5) x 106 B{bar B} pairs collected with the BABAR detector located at the PEP-II B Factory at the Stanford Linear Accelerator Center. We determine the CP-odd fraction of the B° --> D*D*− decays to be R(up tack) = 0.158 ± 0.028 ± 0.006 and find CP asymmetry parameters for the CP-even component of the decay S+ = -0.76 ± 0.16 ± 0.04 and C+ = 0.00 ± 0.12 ± 0.02. We measure S = -0.63±0.36±0.05 and C = -0.07±0.23±0.03 for B° --> DD−, S = -0.62±0.21±0.03 and C = 0.08 ± 0.17 ± 0.04 for B° --> D*+D−, and S = -0.73 ± 0.23 ± 0.05 and C = 0.00 ± 0.17 ± 0.03 for B° --> D+D*−. For the B° --> D*{sup ±}D{sup {-+}} decays, we also determine the CP-violating asymmetry A = 0.008 ± 0.048 {+-} 0.013. In each case, the first uncertainty is statistical and the second is systematic. The measured values for the asymmetries are all consistent with the Standard Model.

Book Description
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.

Book Description
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).

Book Description
The authors present a measurement of time-dependent CP asymmetries and an updated determination of the CP-odd fraction in the decay B° --> D*D*−. The measurements are derived from a data sample of 88 x 106 B{bar B} pairs collected by the BaBar detector at the PEP-II energy asymmetric B Factory at SLAC. All results are preliminary.

We present a measurement of the time-dependent CP-violating asymmetries in B° → K*°[gamma](K*° → 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 the Stanford Linear Accelerator Center. In a sample containing 105 ± 14 signal decays, we measure S{sub K*{sub {gamma}}} = 0.25 ± 0.63 ± 0.14 and C{sub K*{sub {gamma}}} = -0.57 ± 0.32 ± 0.09, where the first error is statistical and the second systematic.

Book Description
The authors present preliminary measurements of the Cp asymmetry parameters and CP content in B{sup 0} {yields} K{sup +}K{sup -}K{sub L}{sup 0} decays, with B{sup 0} {yields} {phi}K{sub L}{sup 0} events excluded. In a sample of 227 M B{bar B} pairs collected by the BABAR detector at the PEP-II B Factory at SLAC, they find the CP parameters to be S = 0.07 {+-} 0.28(stat){sub -0.12}{sup +0.11}(syst); C = 0.54 {+-} 0.22(stat){sub -0.09}{sup +0.08}(syst) where the first error is statistical and the second is systematic. Estimating the fraction of CP-odd final states from angular moments analysis in the K{sup +}K{sup -}K{sub S}{sup 0} CP-conjugate final state, f{sub odd}(K{sup +}K{sup -}K{sub L}{sup 0}) = 0.92 {+-} 0.07(stat) {+-} 0.06(syst), they determine sin2{beta}{sub eff} = 0.09 {+-} 0.33(stat){sub -0.14}{sup +0.13}(syst) {+-} 0.10(syst CP-cont) where the last error is due to uncertainty on the CP content.
