Abstract
We present new measurements of CP-violation parameters in B0→K0, K+K-KS0, f0(980)KS0, η′KS0, ωKS0, and KS0π0 decays based on a sample of 275×106 BB̄ pairs collected at the Υ(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. The combined result for the B0→K0, K+K-KS0, f0(980)KS0, η′KS0, ωKS0, KS0π0, and previously reported KS0KS0KS0 decays..
