Abstract

We perform an amplitude analysis of the decays B0 → K2*(1430)0, K*(892)0, and (Kπ)S-wave0 with a sample of about 384×106 BB̄ pairs recorded with the BABAR detector. The fractions of longitudinal polarization fL of the vector-tensor and vector-vector decay modes are measured to be 0.853-0.069+0.061±0.036 and 0.506±0.040±0.015, respectively. Overall, twelve parameters are measured for the vector-vector decay and seven parameters for the vector-tensor decay, including the branching fractions and parameters sensitive to CP violation. © 2007 The American Physical Society.
