Abstract: (Springer)
We present phenomenological results for ttj t\overline{t}j + X production at the Large Hadron Collider, of interest for designing forthcoming experimental analyses of this process. We focus on those cases where the ttj t\overline{t}j + X process is considered as a signal. We discuss present theoretical uncertainties and the dependence on relevant input parameters entering the computation. For the R \mathcal{R} distribution, which depends on the invariant mass of the ttj t\overline{t}j -system, we present reference predictions in the on-shell, MS \overline{\mathrm{MS}} and MSR top-quark mass renormalization schemes, applying the latter scheme to this process for the first time. Our conclusions are particularly interesting for those analyses aiming at extracting the top-quark mass from cross-section measurements.
