Angular analysis of the decay B+ →k+μ+μ- in proton-proton collisions at s =8 TeV
The angular distribution of the flavor-changing neutral current decay Bþ → Kþμþμ− 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 forwar...

| description | The angular distribution of the flavor-changing neutral current decay Bþ → Kþμþμ− 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 forwardbackward 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 |
