Abstract
We present a measurement of CP-violation parameters in the B-0 ->(KSKSKS0)-K-0-K-0 decay based on a sample of 275x10(6) B (b) over bar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One neutral B meson is fully reconstructed in the decay B-0 ->(KSKSKS0)-K-0-K-0, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters are obtained from the asymmetry in the distributions of the proper-time interval between the two B decays: S = +1.26 +/- 0.68(stat) +/- 0.20(syst) and lambda = +0.54 +/- 0.34(stat) +/- 0.09(syst).
