Book Description
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]).

Book Description
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]).

Book Description
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. We interpret the results in terms of the angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle, and set the bound

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 a new measurement of the time-dependent CP asymmetry of B° →D*D*− decays using (471 ± 5) million B{bar B} pairs collected with the BABAR detector at the PEP-II B Factory at the SLAC National Accelerator Laboratory. Using the technique of partial reconstruction, we measure the time-dependent CP asymmetry parameters S = -0.34 ± 0.12 ± 0.05 and C = +0:15 ± 0.09 ± 0.04. Using the value for the CP-odd fraction R⊥ = 0.158 ± 0.028 ± 0.006, previously measured by BABAR with fully reconstructed B° → D{sup *+}D{sup *-} events, we extract the CP-even components S+ = -0.49 ± 0.18 ± 0.07 ± 0.04 and C+ = +0.15 ± 0.09 ± 0.04. In each case, the first uncertainty is statistical and the second is systematic; the third uncertainty on S+ is the contribution from the uncertainty on R⊥. The measured value of the CP-even component S+ is consistent with the value of sin 2? measured in b → (c{bar c})s transitions, and with the Standard Model expectation of small penguin contributions.
