Abstract
Angular distributions of the decay B+→ K?(892)+μ+μ? are studied using events collected with the CMS detector in s = 8 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 20.0 fb?1. The forward-backward asymmetry of the muons and the longitudinal polarization of the K?(892)+ meson are determined as a function of the square of the dimuon invariant mass. These are the first results from this exclusive decay mode and are in agreement with a standard model prediction. [Figure not available: see fulltext.] ? 2021, The Author(s).
