We use theoretical predictions calculated at next-to-leading order accuracy in quantum chromodynamics to study the (normalized) differential distribution of the $t\bar{t} + 1\mbox{-jet}$ cross section with respect to its invariant mass $\sqrt{s_{t\bar{t} j}}$. The sensitivity of the method to the top-quark mass together with the impact of various theoretical and experimental uncertainties has been…
