- Аннотация: The angular distribution and differential branching fraction of the decay B0→K∗0μ+μ− are studied using a data sample, collected by the LHCb experiment in pp collisions at s√=7TeV, corresponding to an integrated luminosity of 1.0fb−1. Several angular observables are measured in bins of the dimuon invariant mass squared, q2. A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be q20=4.9±0.9GeV2/c4, where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions.
