We present a measurement of CP-violation parameters in the b⃗sq̅ q penguin transitions (q=s,u,d) based on a 78fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is reconstructed in the φKS0, K+K-KS0, or η′KS0 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.
