Abstract

We report improved measurements of time-dependent CP violation parameters for B0 (B0) → (2S)K0S . This analysis is based on a data sample of 657×106 BB pairs collected at the γ(4S) res- onance with the Belle detector at the KEKB energy-asymmetric e+e- collider. We fully reconstruct one neutral B meson in the (2S)K0 S CP-eigenstate decay channel, and the flavor of the accompa- nying B meson is identified to be either B0 or B0 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: S (2S)K0 S = +0.72 ± 0.09(stat) ± 0.03(syst), A (2S)K0S = +0.04 ± 0.07(stat) ± 0.05(syst). These results are in agreement with results from measurements of B0 → J/ ψ K0.

N2 - We report improved measurements of time-dependent CP violation parameters for B0 (B0) → (2S)K0S . This analysis is based on a data sample of 657×106 BB pairs collected at the γ(4S) res- onance with the Belle detector at the KEKB energy-asymmetric e+e- collider. We fully reconstruct one neutral B meson in the (2S)K0 S CP-eigenstate decay channel, and the flavor of the accompa- nying B meson is identified to be either B0 or B0 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: S (2S)K0 S = +0.72 ± 0.09(stat) ± 0.03(syst), A (2S)K0S = +0.04 ± 0.07(stat) ± 0.05(syst). These results are in agreement with results from measurements of B0 → J/ ψ K0.
