Abstract
We report improved measurements of time-dependent CP violation parameters for B^0 -> psi(2S) K_S. This analysis is based on a data sample of 657x10^6 BBbar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. CP violation parameters are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays S (psi(2S) K_S) = +0.72 +/- 0.09(stat) +/- 0.03(syst) A (psi(2S) K_S) = +0.04 +/- 0.07(stat) +/- 0.05(syst) and are in agreement with results from measurements of B^0 -> J/psi K^0.
