Abstract (data abstract)
CERN-LHC. CMS. The angular distribution of the flavor-changing neutral current decay B+ to K+ μ+ μ- is studied in proton-proton collisions at a center-of-mass energy of 8 TeV. The analysis is based on data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5$fb^{-1}$. The forward-backward asymmetry $A_{FB}$ of the dimuon system and the contribution $F_{H}$ from the pseudoscalar, scalar, and tensor amplitudes to the decay width are measured as a function of the dimuon mass squared. The measurements are consistent with the standard model expectations.
