Abstract
We perform the first measurement on the mixing parameters using a time-dependent amplitude analysis of the decay . The data were recorded with the BABAR detector at center-of-mass energies at and near the resonance, and correspond to an integrated luminosity of approximately . The neutral meson candidates are selected from decays where the flavor at the production is identified by the charge of the low-momentum pion, . The measured mixing parameters are and , where the quoted uncertainties are statistical and systematic, respectively.
