Measurement of time-dependent CP violation parameters in B-0 -> (KSKSKS0)-K-0-K-0 decays at Belle
Original language description
We measure the time-dependent CP violation parameters in B-0 -> (KSKSKS0)-K-0-K-0 decays using 772 x 10(6)B (B) over bar pairs collected at the Upsilon(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.
