Abstract: This document presents projections for the top quark pole mass measurement in $t\bar t $+ 1 jet events at the High Luminosity Large Hadron Collider (HL-LHC). These projections are based on the measurement of the top quark pole mass in $t\bar t $+ 1 jet events collected with the ATLAS detector in proton–proton collisions at $\sqrt{s}=8$ TeV. The HL-LHC projection accounts for statistical uncertainty improvements due to the large data set available at the HL-LHC, as well as a reduction in systematic uncertainties which is foreseen from both theoretical and experimental developments. A projected uncertainty on $m_{t}^\text{pole}$ of 600 MeV is obtained without profiling systematic uncertainties.
