Measurement of CP-Violating Parameters in Fully Reconstructed B to D(*)+-pi-+ and B to D+-rho-+ Decays
The authors present a preliminary measurement of the CP-violating parameters in fully reconstructed B{sup 0} {yields} D{sup (*){+-}}{pi}{sup {-+}} and B{sup 0} {yields} D{sup {+-}}{rho}{sup {-+}} decays in approximately 232 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC.
Measurement of CP-violating Parameters in Fully Reconstructed B--]D(*)pi and B--]Drho Decays
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).
