Abstract: | We report a measurement of C P -violating asymmetries in B 0 → ( ρ π ) 0 → π + π − π 0 decays using a time-dependent Dalitz plot analysis. The results are obtained from a data sample of 375 × 10 6 Υ ( 4 S ) → B ¯¯¯ B decays, collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure 26 coefficients of the bilinear form-factor terms occurring in the time-dependent decay rate of the B 0 meson. We derive the physically relevant quantities from these coefficients. In particular, we measure a constraint on the angle α of the unitarity triangle. |
