英文摘要	We present an improved measurement of cp-violation parameters in b(0)-->phik(s)(0), k(+)k(-)k(s)(0), and eta(')k(s)(0) decays 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 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 three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two b decays. we find that the observed cp asymmetry in the b-->phik(s)(0) decay differs from the standard model (sm) expectation by 3.5 standard deviations, while the other cases are consistent with the sm.
