The authors present a preliminary measurement of the time-dependent CP-violating asymmetry in decays of neutral B mesons to the final states D*[sup [-+]][pi][sup [+-]], using approximately 178 million B[bar B] events recorded by the BABAR experiment at the PEP-II d[sup +]e[sup -] storage ring. Events containing these decays are selected with a partial reconstruction technique, in which only the high-momentum [pi][sup [+-]] from the B decay and the low-momentum [pi][sup [-+]]. from the D*[sup [-+]]. decay are used. They measure the amplitude of the asymmetry to be -0.041 [+-] 0.016 (stat.) [+-] 0.010 (syst.) and determine bounds on sin(2[beta]+[gamma]).

While the measurement of sin2[beta] is now a precision measurement, the constraints on the other two angles of the Unitarity Triangle, [alpha] and [gamma], are still limited by statistics and/or by theoretical uncertainties. This paper reports on the measurement of CP-violating asymmetries in B[sup 0] --> D(*)[sup [+-]][pi][sub [-+]] and B[sup 0] --> D[sup [+-]][rho][sup [-+]] decays in [Upsilon](4S) --> B[bar B] decays, asymmetries which are rleated to sin(2[beta] + [gamma]). This analysis updates the results already published by including a new decay mode (B[sup 0] --> D[sup [+-]][rho][sup [-+]]) and a larger data sample (110 instead of 88 million [Upsilon](4S) --> B[bar B] decays).

We present a preliminary measurement of time-dependent CP-violating asymmetries in fully reconstructed B° → D*{sup {+-}[pi]{sup -+}} decays in a data sample of approximately 88 million [Upsilon](4S) → B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC.

The authors present a preliminary measurement of the time-dependent CP asymmetries in decays of neutral B mesons to the final states D*[sup[-+]][pi][sup[+-]], using approximately 82 million B[bar B] events collected by the BABAR experiment at the PEP-II storage ring. Events containing these decays are selected with a partial reconstruction technique, in which only the high momentum[pi][sup[+-]] and the low momentum pion from the D*[sup[-+]] decay are reconstructed. The flavor of the other B meson in the event is tagged using the information from kaon and lepton candidates. They measure the time-dependent CP asymmetry[Alpha]= -0.063[+-] 0.024 (stat.)[+-] 0.017 (syst.). They interpret these results in terms of the angles of the unitarity triangle to set a bound onsin(2[beta]+[gamma]).

We present a measurement of time-dependent CP-violating asymmetries in neutral B meson decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The data sample consists of 29.7 fb[sup -1] recorded at the[Upsilon](4S) resonance and 3.9 fb[sup -1] off-resonance. One of the neutral B mesons, which are produced in pairs at the[Upsilon](4S), is fully reconstructed in the CP decay modes J/[psi] K[sub S][sup 0], [psi](2S) K[sub S][sup 0], [chi][sub c1] K[sub S][sup 0], J/[psi] K*[sup 0] (K*[sup 0][yields] K[sub S][sup 0][pi][sup 0]) and J/[psi] K[sub L][sup 0], or in flavor-eigenstate modes involving D(*)[pi]/[rho]/[sub 1] and J/[psi] K*[sup 0] (K*[sup 0][yields] K[sup+][pi][sup -]). The flavor of the other neutral B meson is tagged at the time of its decay, mainly with the charge of identified leptons and kaons. A neural network tagging algorithm is used to recover events without a clear lepton or kaon tag. The proper time elapsed between the decays is determined by measuring the distance between the decay vertices. Wrong-tag probabilities, the time-difference resolution function, and the B[sup 0]-[bar B][sup 0] oscillation frequency[Delta]m[sub d]are measured with a sample of about 6350 fully-reconstructed B[sup 0] decays in hadronic flavor-eigenstate modes. A maximum-likelihood fit to this flavor eigenstate sample finds[Delta]m[sub d]= 0.516[+-] 0.016 (stat)[+-] 0.010 (syst) ps[sup -1]. The value of the asymmetry amplitude sin2[beta] is determined from a simultaneous maximum-likelihood fit to the time-difference distribution of the flavor-eigenstate sample and about 642 tagged B[sup 0] decays in the CP-eigenstate modes. We find sin2[beta]= 0.59[+-] 0.14 (stat)[+-] 0.05 (syst), demonstrating that CP violation exists in the neutral B meson system. We also determine the value of the CP violation parameter[lambda]= 0.93[+-] 0.09 (stat)[+-] 0.03 (syst), which is consistent with the expectation of[lambda]= 1 for no direct CP violation.

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
