We perform an amplitude analysis of the decays B0→ϕK2*(1430)0, ϕK*(892)0, and ϕ(Kπ)S-wave0 with a sample of about 384×10^6 BB̅ 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.

Abstract
We perform an amplitude analysis of the decays B0→ϕK2*(1430)0, ϕK*(892)0, and ϕ(Kπ)S-wave0 with a sample of about 384×10^6 BB̅ 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.File in questo prodotto:
