Angular distributions of the decay B$^+$ $$\to$$ K$^*$(892)$$^+\mu^+\mu^-$$ are studied using events collected with the CMS detector in $$\sqrt{s} =$$ 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$$^\ast$$(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.
