Measurement of polarization amplitudes and CP asymmetries in B ⁰ → Φk ^*(892)⁰

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 sqrt{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 {overline{B}} 0}\to \phi {overline{K}} {*}}{left({892} \right)} 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.
