An angular analysis of the B0→K*0 μ+μ− decay is performed in pp collisions at √s = 7 TeV, with a data sample corresponding to an integrated luminosity of 5.2 fb−1 collected by the CMS experiment at the LHC. The forward-backward asymmetry of the muons AFB, the K*0 longitudinal polarization fraction FL, and the differential branching fraction dℬ/dq2, are measured as function of the dimuon invariant mass squared, q2. The results are in good agreement with the standard model expectations.
