Abstract
An angular analysis of the decay B 0 → ΦK *(892)0 is reported based on a pp collision data sample, corresponding to an integrated luminosity of 1.0 fb-1, collected at a centre-of-mass energy of √s = 7 TeV with the LHCb detector. The P-wave amplitudes and phases are measured with a greater precision than by previous experiments, and confirm about equal amounts of longitudinal and transverse polarization. The S-wave K + π - and K + K - contributions are taken into account and found to be significant. A comparison of the B 0 → ΦK *(892)0 and B-0 → ΦK-*(892)0 results shows no evidence for direct CP violation in the rate asymmetry, in the triple-product asymmetries or in the polarization amplitudes and phases.
