Abstract
We perform an amplitude analysis of decay with a sample of about pairs recorded with the BABAR detector. Overall, twelve parameters are measured, including the fractions of longitudinal and parity-odd transverse amplitudes, branching fraction, strong phases, and six parameters sensitive to violation. We use the dependence on the invariant mass of the interference between the and components to resolve the discrete ambiguity in the determination of the strong and weak phases. Our measurements of , , and the strong phases point to the presence of a substantial helicity-plus amplitude from a presently unknown source.
