dc.description.abstract	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.	en
