Abstract

We measure the time-dependent CPviolation parameters in B0 → K0 S K0 S K0 S decays using 772 × 106 BB̅ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e collider. The obtained mixing-induced and direct CP asymmetries are −0.71 ± 0.23 (stat) ± 0.05 (syst) and 0.12 ± 0.16 (stat) ± 0.05 (syst), respectively. These values are consistent with the Standard Model predictions. The significance of CP violation differs from zero by 2.5 standard deviations.
