Abstract: | 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 √ 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 B0 → 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. |
