dc.description.abstract | We report the results of a C P violation analysis of the decay B ± → D π + π − π 0 K ± , where D π + π − π 0 indicates a neutral D meson detected in the final state π + π − π 0 , excluding K 0 S π 0 . The analysis makes use of 324 × 10 6 e + e − → B ¯¯¯ B events recorded by the BABAR experiment at the PEP-II e + e − storage ring. Analyzing the π + π − π 0 Dalitz plot distribution and the B ± → D π + π − π 0 K ± 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 < r B < 0.78 , − 30 ° < γ < 76 ° , − 27 ° < δ < 78 ° . We also measure the magnitudes and phases of the components of the D 0 → π + π − π 0 decay amplitude. | - |
