Angular distributions of the decay B⁺ → K*(892)⁺μ⁺μ^- are studied using events collected with the CMS detector in √s = 8 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 20.0 fb^-1. The forward-backward asymmetry of the muons and the longitudinal polarization of the K*(892)⁺ meson are determined as a function of the square of the dimuon invariant mass. These are the first results from this exclusive decay mode and are in agreement with a standard model prediction.
