N2 - The first measurement of the (Formula presented) asymmetry of the decay rate ((Formula presented)) and the (Formula presented) average ((Formula presented)) and (Formula presented) asymmetry ((Formula presented)) of the forward-backward asymmetry in the muon system of (Formula presented) decays is reported. The measurement is performed using a data sample of proton-proton collisions, recorded by the LHCb experiment from 2016 to 2018 at a center-of-mass energy of 13 TeV, which corresponds to an integrated luminosity of (Formula presented). The asymmetries are measured in two regions of dimuon mass near the (Formula presented)-meson mass peak. The dimuon-mass integrated results are (Formula presented), (Formula presented), (Formula presented), where the first uncertainty is statistical and the second systematic. The results are consistent with the conservation of (Formula presented) symmetry and the Standard Model expectations.
