Abstract

We perform a time-dependent amplitude analysis of B0→KS0π+π- decays to extract the CP violation parameters of f0(980)KS0 and ρ0(770)KS0 and the direct CP asymmetry of K*+(892)π-. The results are obtained from a data sample of (383±3)×106 BB̄ decays, collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We find two solutions, with an equivalent goodness-of-fit. Including systematic and Dalitz plot model uncertainties, the combined confidence interval for values of the CP parameter βeff in B0 decays to f0(980)KS0 is 18°
