Angular analysis of the decay B%2b → K∗(892)%2b μ %2b μ − in proton-proton collisions at √s = 8 TeV

Angular distributions of the decay B%2b→ K∗(892)%2bμ%2bμ− 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)%2b 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).
