| Abstract | We perform a time-dependent Dalitz plot analysis of B0 → K0 Sππ in order to extract the CP violation parameters of f0(980)K 0 S and ρ 0(770)K0 S and direct CP -asymmetries of K ∗+(892)π−. The results are obtained from a data sample of (383 ± 3) × 106 BB decays, collected with the BABAR detector at the PEP-II asymmetric–energy B factory at SLAC. The measured values of 2βeff in B 0 decays to f0(980)K 0 S and ρ 0(770)K0 S are (89 +22 −20 ± 5± 8)◦ and (37 −17 ± 5± 6)◦, respectively, where the first quoted uncertainty is statistical, the second is systematic and the third is Dalitz plot signal model uncertainty. We measure the significance of 2βeff (f0(980)K 0 S) 6= 0 to be 4.3σ. In decays to K∗(892)π we find ACP = −0.18 ± 0.10 ± 0.03 ± 0.03. The measured phase difference between the decay amplitudes of B0 → K∗+(892)π− and B0 → K∗−(892)π+ is (−164 ± 24 ± 12 ± 15)◦. All results are preliminary.
