Abstract
We report a search for CP-violating asymmetry in B-0-->D*+/-D-/+ decays. The analysis employs two methods of B-0 reconstruction: full and partial. In the full reconstruction method all daughter particles of the B-0 are required to be detected; the partial reconstruction technique requires a fully reconstructed D- and only a slow pion from the D*+-->D(0)pi(slow)(+) decay. From a fit to the distribution of the time interval corresponding to the distance between two B meson decay points we calculate the CP-violating parameters and find the significance of nonzero CP asymmetry to be 2.7 standard deviations.
