摘要：

We present a measurement of the CP violation parameters in B-0 -> K-S(0)pi(0)pi(0) and B-0 -> (KSKS0)-K-0 decays using a data sample containing 657 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider operating at the gamma(4S) resonance. We obtain S-KS(pi)pi(0)0(0) = +0.43 +/- 0.49 +/- 0.09, A(KS)(pi)(pi)(0)(0)(0) = -0.17 +/- 0.24 +/- 0.06, S-KS(KS)0(0) = -0.38 +/- 0.77 +/- 0.08 and A(KS)(KS)(0)(0) = -0.38 +/- 0.38 +/- 0.05, where the first and second errors are statistical and systematic, respectively.
