Title: Vector-Tensor and Vector-Vector Decay Amplitude Analysis of B{sup 0}{yields}{phi}K{sup *0}

Abstract

We perform an amplitude analysis of the decays B{sup 0}{yields}{phi}K{sub 2}{sup *}(1430){sup 0}, {phi}K{sup *}(892){sup 0}, and {phi}(K{pi}){sub S-wave}{sup 0} with a sample of about 384x10{sup 6} BB pairs recorded with the BABAR detector. The fractions of longitudinal polarization f{sub L} of the vector-tensor and vector-vector decay modes are measured to be 0.853{sub -0.069}{sup +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.
