Abstract

We present measurements of time-dependent CP asymmetries in B0→ωKS0, f0(980)KS0, KS0π0 and K+K-KS0 decays based on a sample of 535×106 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.
