The angular distributions and the differential branching fraction of the decay B⁰→K^*(892)⁰μ⁺μ^- are studied using data corresponding to an integrated luminosity of 20.5 fb^-1 collected with the CMS detector at the LHC in pp collisions at s=8 TeV. From 1430 signal decays, the forward-backward asymmetry of the muons, the K^*(892)⁰ longitudinal polarization fraction, and the differential branching fraction are determined as a function of the dimuon invariant mass squared. The measurements are among the most precise to date and are in good agreement with standard model predictions.
