dc.description.abstract | We present a measurement of form-factor-independent angular observables in the decay B 0 → K ∗ ( 892 ) 0 μ + μ − . The analysis is based on a data sample corresponding to an integrated luminosity of 1.0 fb − 1 , collected by the LHCb experiment in p p collisions at a center-of-mass energy of 7 TeV. Four observables are measured in six bins of the dimuon invariant mass squared q 2 in the range 0.1 < q 2 < 19.0 GeV 2 / c 4 . Agreement with recent theoretical predictions of the standard model is found for 23 of the 24 measurements. A local discrepancy, corresponding to 3.7 Gaussian standard deviations is observed in one q 2 bin for one of the observables. Considering the 24 measurements as independent, the probability to observe such a discrepancy, or larger, in one is 0.5%. | - |
