      abstract     = {A measurement of the top-quark pole mass
                      $m_{t}^\text{pole}$ is presented in $t\bar{t}$ events with
                      an additional jet, $t\bar{t}+1\text{-jet}$, produced in $pp$
                      collisions at $\sqrt{s}=13$ TeV. The data sample, recorded
                      with the ATLAS experiment during Run 2 of the LHC,
                      corresponds to an integrated luminosity of 140
                      $\text{fb}^{-1}$. Events with one electron and one muon of
                      opposite electric charge in the final state are selected to
                      measure the $t\bar{t}+1\text{-jet}$ differential
                      cross-section as a function of the inverse of the invariant
                      mass of the $t\bar{t}+1\text{-jet}$ system. Iterative
                      Bayesian Unfolding is used to correct the data to enable
                      comparison with fixed-order calculations at
                      next-to-leading-order accuracy in the strong coupling. The
                      process $pp \to t\bar{t}j$ ($2 \rightarrow 3$), where top
                      quarks are taken as stable particles, and the process $pp
                      \to b\bar{b}l^+νl^- \barν j$ ($2 \to 7$), which includes
                      top-quark decays to the dilepton final state and off-shell
                      effects, are considered. The top-quark mass is extracted
                      using a $χ^2$ fit of the unfolded normalized differential
                      cross-section distribution. The results obtained with the $2
                      \to 3$ and $2 \to 7$ calculations are compatible within
                      theoretical uncertainties, providing an important
                      consistency check. The more precise determination is
                      obtained for the $2 \to 3 $ measurement:
                      $m_{t}^\text{pole}=170.7\pm0.3(\text{stat.})\pm1.4(\text{syst.})\pm
                      0.3(\text{scale})\pm 0.2(\text{PDF}\oplusα_\text{S})$ GeV,
                      which is in good agreement with other top-quark mass
                      results.},
