摘要
We report on measurements of time-dependent, CP-violation parameters in neutral B meson systems based on a 140 fb(-1) data sample collected at the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One B meson is fully reconstructed in one of the CP eigenstate decay channels, and its flavor is identified from the decay products of the accompanying B meson. The CP-violation parameters are extracted from the asymmetries in the distributions of the proper-time intervals between the two B decays. The parameter sin 2 phi(1) is measured with the decay modes including the b -> c tree and b -> s penguin transitions, and sin 202 is obtained from the decay mode B -> pi(+)pi(-). A brief discussion of the phi(3) measurements with B -> D(*) (-/+)pi(+/-) decays is also given.
