Abstract
We present measurements of decay amplitudes and triple-product correlations in B ->phi K-* decays based on 253 fb(-1) of data recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) storage ring. The decay amplitudes for the three different helicity states are determined from the angular distributions of final-state particles. The longitudinal polarization amplitudes are found to be 0.45 +/- 0.05 +/- 0.02 for B-0->phi K-*0 and 0.52 +/- 0.08 +/- 0.03 for B+->phi K*+ decays. CP- and T-odd CP-violating triple-product asymmetries are measured to be consistent with zero.
