Abstract
We present a measurement of -violation parameters in the penguin transitions based on a data sample collected at the resonance with the Belle detector at the KEKB energy-asymmetric collider. One neutral B meson is reconstructed in the or decay channel, and the flavor of the accompanying B meson is identified from its decay products. violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.
