    <description descriptionType="Abstract">&lt;p&gt;A search for the associated production of a heavy resonance with a top-quark or a top-antitop-quark pair, and decaying into a     $t\overline{t}$   pair is presented. The search uses the data recorded by the ATLAS detector in pp collisions at     $\sqrt{s}=13$       $\text{TeV}$   at the Large Hadron Collider during the years 2015–2018, corresponding to an integrated luminosity of 139     ${\text{fb}}^{-1}$  . Events containing exactly one electron or muon are selected. The two hadronically decaying top quarks from the resonance decay are reconstructed using jets clustered with a large radius parameter of     $R=1$  . The invariant mass spectrum of the two top quark candidates is used to search for a resonance signal in the range of 1.0     $\text{TeV}$   to 3.2     $\text{TeV}$  . The presence of a signal is examined using an approach with minimal model dependence followed by a model-dependent interpretation. No significant excess is observed over the background expectation. Upper limits on the production cross section times branching ratio at 95% confidence level are provided for a heavy     ${Z}^{\prime }$   boson based on a simplified model, for     ${Z}^{\prime }$   mass between 1.0     $\text{TeV}$   and 3.0     $\text{TeV}$  . The observed (expected) limits range from 21 (14) fb to 119 (86) fb depending on the choice of model parameters.&lt;/p&gt;</description>
