Abstract

We present a measurement of CP-violation parameters in the B0→KS0KS0KS0 decay based on a sample of 275×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is fully reconstructed in the decay B0→KS0KS0KS0, 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 A=+0.54±0. 34(stat)±0.09(syst). © 2005 The American Physical Society.
