Abstract
We perform amplitude analyses of the decays , , and , and measure -violating parameters and partial branching fractions. The results are based on a data sample of approximately decays, collected with the BABAR detector at the PEP-II asymmetric-energy factory at the SLAC National Accelerator Laboratory. For , we find a direct asymmetry in of , which differs from zero by . For , we measure the -violating phase . For , we measure an overall direct asymmetry of . We also perform an angular-moment analysis of the three channels and determine that the state can be described well by the sum of the resonances , , and .
