Measurement of polarization amplitudes and CP asymmetries in B0 → ϕ K[bar][ast](892)0

An angular analysis of the decay B0 → 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 pre...

Description
Summary:An angular analysis of the decay B0 → 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 B0 → 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.
