Abstract
We present results on time-dependent asymmetries in neutral decays to several eigenstates. The measurements use a data sample of about decays collected by the BABAR detector at the PEP-II asymmetric-energy Factory at SLAC. The amplitude of the asymmetry, in the standard model, is derived from decay-time distributions from events in which one neutral meson is fully reconstructed in a final state containing a charmonium meson and the other meson is determined to be either a or from its decay products. We measure in agreement with the standard model expectation.
