Angular analysis and branching fraction measurement of the decay B0→K*0μ+μ−

The angular distributions and the differential branching fraction of the decay B0→K*(892)0μ+μ− are studied using a data sample corresponding to an integrated luminosity of 5.2 fb−1collected with the CMS detector at the LHC in pp collisions at √s=7 TeV. From more than 400 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 square of the dimuon invariant mass. The measurements are in good agreement with standard model predictions.
