Abstract
We present a measurement of form-factor-independent angular observables in the decay B[superscript 0] → K[superscript *](892)[superscript 0]μ[superscript +]μ[superscript −]. The analysis is based on a data sample corresponding to an integrated luminosity of 1.0  fb[superscript −1], collected by the LHCb experiment in pp collisions at a center-of-mass energy of 7 TeV. Four observables are measured in six bins of the dimuon invariant mass squared q[superscript 2] in the range 0.1 < q[superscript 2] < 19.0  GeV[superscript 2]/c[superscript 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[superscript 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%.
