Abstract

We report improved measurements of time-dependent CP violation parameters for B0(B̄0)→ψ(2S)KS0. This analysis is based on a data sample of 657×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. We fully reconstruct one neutral B meson in the ψ(2S)KS0 CP-eigenstate decay channel, and the flavor of the accompanying B meson is identified to be either B0 or B̄0 from its decay products. CP violation parameters are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays: Sψ(2S)KS0=+0.72±0.09(stat)±0.03(syst), Aψ(2S)KS0=+0.04±0.07(stat)±0.05(syst). These results are in agreement with results from measurements of B0→J/ψK0.
