Angular analysis of the decay B0?K*0?+?- from pp collisions at s=8 TeV

Abstract: The angular distributions and the differential branching fraction of the decay B0?K*(892)0?+?- are studied using data corresponding to an integrated luminosity of 20.5 fb-1 collected with the CMS detector at the LHC in pp collisions at s=8 TeV. From 1430 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 dimuon invariant mass squared. The measurements are among the most precise to date and are in good agreement with standard model predictions.
