Vector-Tensor and Vector-Vector Decay Amplitude Analysis of B0->phi K*0
The BABAR Collaboration, B. Aubert
Abstract
We perform an amplitude analysis of the decays B0->phi K*2(1430)0, phi K*(892)0, and phi(K pi)0S-wave with a sample of about 384 million BBbar 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 +0.061-0.069 +-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.
