Abstract
We perform a time-dependent amplitude analysis of decays to extract the violation parameters of and and the direct asymmetry of . The results are obtained from a data sample of decays, collected with the BABAR detector at the PEP-II asymmetric–energy factory at SLAC. We find two solutions, with an equivalent goodness-of-fit. Including systematic and Dalitz plot model uncertainties, the combined confidence interval for values of the parameter in decays to is at 95% confidence level (C.L). conservation in decays to is excluded at 3.5 standard deviations including systematic uncertainties. For decays to , the combined confidence interval is at 95% C.L. In decays to we measure the direct asymmetry to be . The measured phase difference (including mixing) between decay amplitudes of and , excludes the interval at 95% C.L.
