Abstract

We report a measurement of the CP-violating parameters in B0→KS0KS0 decays based on a data sample of 657×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. In this Letter, one neutral B meson is fully reconstructed in the B0→KS0KS0 decay mode, and the flavor of the accompanying B meson is identified by its decay products. The CP-violating parameters are measured from the asymmetry in the distributions of the proper-time interval between the two B decays: SKS0KS0=-0.38-0.77+0.69(stat)±0.09(syst) and AKS0KS0=-0.38±0.38(stat)±0.05(syst).

In this Letter, one neutral B meson is fully reconstructed in the B0→KS0KS0 decay mode, and the flavor of the accompanying B meson is identified by its decay products. The CP-violating parameters are measured from the asymmetry in the distributions of the proper-time interval between the two B decays: SKS0KS0=-0.38-0.77+0.69(stat)±0.09(syst) and AKS0KS0=-0.38±0.38(stat)±0.05(syst).
