Differential branching fraction and angular analysis of the decay B 0 → K ∗0 μ + μ -
Abstract
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.
