      abstract     = {The top-quark mass is measured using top-quark decays
                      producing an isolated lepton and $J/ψ$ meson reconstructed
                      in its $μ^+μ^-$ decay mode. The data sample was recorded
                      with the ATLAS detector in proton-proton collisions at a
                      centre-of-mass energy of $\sqrt{s}=13$ TeV during Run 2 of
                      the Large Hadron Collider, corresponding to an integrated
                      luminosity of 140 fb$^{-1}$. The measurement is based on the
                      invariant mass $m(\ell μ^+μ^-)$ of the system made of the
                      isolated lepton $\ell$ from the $W$ boson decay and the
                      non-isolated $μ^+μ^-$ pair from a $J/ψ$ decay of a
                      $b$-hadron, exploiting its sensitivity to the top-quark
                      mass. An unbinned maximum-likelihood fit to the $m(\ell
                      μ^+μ^-)$ distribution is performed to extract the
                      top-quark mass. The top-quark mass is measured to be
                      $m_{top} = 172.17 \pm 0.80 (stat) \pm 0.81 (syst) \pm 1.07
                      (recoil)$ GeV, with a total uncertainty of 1.56 GeV. The
                      third uncertainty arises from changing the dipole parton
                      shower gluon-recoil scheme used in top-quark decays.},
