Abstract
We perform a time-dependent and time-integrated angular analysis of the decays , , and with the final sample of about pairs recorded with the BABAR detector. Twenty-four parameters are investigated, including the branching fractions, -violation parameters, and parameters sensitive to final-state interactions. We use the dependence on the invariant mass of the interference between the scalar and vector or tensor components to resolve discrete ambiguities of the strong and weak phases. We use the time evolution of the channel to extract the -violation phase difference between the and decay amplitudes. When the channel is included, the fractions of longitudinal polarization of the vector-vector and vector-tensor decay modes are measured to be and , respectively. This polarization pattern requires the presence of a positive-helicity amplitude in the vector-vector decay from a currently unknown source.
