### Description

We present results for the NLO QCD corrections to the process $pp \to t\bar{t} j \to W^+W^-b\bar{b} j \to e^+ \nu_e \mu^- \bar{\nu}_\mu b \bar{b} j + X$, including for the first time the full off-shell effects for top quarks and W bosons: double-, single- and non-resonant contributions at the order {\cal{O}}(\alpha_{s}^4 \alpha^4). Focusing on the case of the LHC at 8 TeV, we analyse numerical results for the total cross section and its scale dependence, and show differential distributions. We also provide an estimate of the impact of the off-shell effects within our study.
