Angular analysis of the decay B+ ?k+?+?- in proton-proton collisions at s =8 TeV

Abstract: The angular distribution of the flavor-changing neutral current decay B+?K+?+?- 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 AFB of the dimuon system and the contribution FH 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.
