Differential branching fraction and angular analysis of the decay $B^{0} \to K^{*0} \mu^{+}\mu^{-}$

The angular distribution and differential branching fraction of the decay B (0)→ K (∗0) μ (+) μ (−) are studied using a data sample, collected by the LHCb experiment in pp collisions at TeV, corresponding to an integrated luminosity of 1.0 fb(−1). Several angular observables are measured in bins of the dimuon invariant mass squared, q (2). 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 , where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions.
