## Abstract

The angular distributions of the rare decays B → K

^{+}µ^{+}µ^{-}and B^{0}→ K^{0}<inf>a</inf>Sμ^{+}μ^{-}are studied with data corresponding to 3 fb^{-1}of integrated luminosity, collected in proton-proton collisions at 7 and 8TeV centre-of-mass energies with the LHCb detector. The angular distribution is described by two parameters, FH and the forward-backward asymmetry of the dimuon system A^{FB}, which are determined in bins of the dimuon mass squared. The parameter F<inf>H</inf> is a measure of the contribution from (pseudo)scalar and tensor amplitudes to the decay width. The measurements of A<inf>FB</inf> and F<inf>H</inf> reported here are the most precise to date and are compatible with predictions from the Standard Model.Original language | English |
