Abstract
We present a measurement of the CP violation parameters in B0 ->Kspi0pi0 and B0 -> KsKs decays using a data sample containing 657x10^6 BBbar pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider operating at the Y(4S) resonance. We measure SKspi0pi0 = +0.43+/-0.49+/-0.09, AKspi0pi0 = -0.17+/-0.24+/-0.06, SKsKs = -0.38+/-0.77+/-0.08 and AKsKs = -0.38+/-0.38+/-0.05, where the first and second errors are statistical and systematic, respectively.
