Abstract

We present a measurement of the CP violation parameters in B0 → K0 S π0π0 and B0 → K0 S K0 S decays using a data sample containing 657 ×106 BB pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider operating at the γ(4S) resonance. We measure SK0 Sπ0π0 = +0.43 ± 0.49 ± 0.09, AK0 Sπ0π0 = -0.17 ± 0.24 ± 0.06, SK0 SK0 S = -0.38 ± 0.77 ± 0.08 and, AK0 SK0 S = -0.38 ± 0.38 ± 0.05, where the first and second errors are statistical and systematic, respectively.
