Aubert, B. et al. (2007) Measurement of CP Violation Parameters with a Dalitz Plot Analysis of B±→Dπ+π-π0K±. Physical Review Letters, 99 (25). p. 251801. ISSN 0031-9007Metadata only available from this repository.
We report the results of a CP violation analysis of the decay B±→Dπ+π-π0K±, where Dπ+π-π0 indicates a neutral D meson detected in the final state π+π-π0, excluding KS0π0. The analysis makes use of 324×106 e+e-→BB̅ events recorded by the BABAR experiment at the PEP-II e+e- storage ring. Analyzing the π+π-π0 Dalitz plot distribution and the B±→Dπ+π-π0K± branching fraction and decay rate asymmetry, we find the following one-standard-deviation constraints on the amplitude ratio and on the weak and strong phases: 0.06<rB<0.78, -30°<γ<76°, -27°<δ<78°. We also measure the magnitudes and phases of the components of the D0→π+π-π0 decay amplitude.
