We perform a time-dependent amplitude analysis of B-0 -> K-S(0)pi(+)pi(-) decays to extract the CP violation parameters of f(0)(980)K-S(0) and rho(0)(770)K-S(0) and the direct CP asymmetry of K*+(892)pi(-). The results are obtained from a data sample of (383 +/- 3)x10(6) BB 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 beta(eff) in B-0 decays to f(0)(980)K-S(0) is 18 degrees K*+(892)pi(-) and B-0 -> K*-(892)pi(+), excludes the interval -137 degrees
  • The results below are discovered through our pilot algorithms. Let us know how we are doing!
