CP Violation Studies in B0 to D(*)+- Pi-+ in BABAR and Belle
- SLAC
The authors present a preliminary measurement of the time-dependent CP asymmetries in decays of B{sup 0} mesons to the final states D{sup (*)}{pi} using data collected by the BABAR experiment at the PEP-II storage rings. B mesons decaying to D{pi} are fully reconstructed, while events containing B {yields} D*{pi} are selected using a full or a partial reconstruction technique. These results can be interpreted in terms of a constraint on the angles of the unitarity triangle to set a lower bound on |sin (2{beta} + {gamma})|. The Belle experiment at the KEK-B collider is performing the same kind of studies and a preliminary estimation of the achievable error is presented.
