英文摘要	We present a measurement of CP-violation parameters in the b-->s (q) over barq penguin transitions (q=s,u,d) based on a 78 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 reconstructed in the phiK(S)(0), (K+K-KS0), or eta'K-S(0) decay channel, 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.
