Abstract
We perform an amplitude analysis of the decays B-0 -> phi K-2(*)(1430)(0), phi K-*(892)(0), and phi(K pi)(s-wave)(0) with a sample of about 384 x 10(6) BB pairs recorded with the BABAR detector. The fractions of longitudinal polarization f(L) of the vector-tensor and vector-vector decay modes are measured to be 0.853 +/- (+0.061)(-0.069) +/- 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.
