摘要

We present measurements of time-dependent CP asymmetries in B-0 ->omega K-S(0), f(0)(980)K-S(0), K-S(0)pi(0) and (K+K-KS0) decays based on a sample of 535x10(6) B (B) over bar pairs 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.
