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). |
