Abstract
We present a precise measurement of the violation parameter and the direct violation parameter using the final data sample of pairs collected at the resonance with the Belle detector at the KEKB asymmetric-energy collider. One neutral meson is reconstructed in a , , , or eigenstate and its flavor is identified from the decay products of the accompanying meson. From the distribution of proper-time intervals between the two decays, we obtain the following violation parameters: and .
