摘要：

We present new measurements of CP-violation parameters in B-0 -> phi K-0, K+K- K-0(S), fo(980)K-S(0), eta'K-S(0), omega K-S(0), K(S)(0)pi(0), and K*(0)(gamma) (K*(0) -> K(S)(0)pi(0)) decays based on a sample of 275 x 10(6) B (B) over bar pair's collected at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. All results are preliminary.
