Abstract

In this proceeding we present predictions for the complete NLO QCD corrections to the production of ttˉbbˉt\bar{t}b\bar{b} in the dilepton decay channel of the top quark at the LHC with s=13\sqrt{s}=13 TeV. The calculation is performed considering all the full off-shell effects. Moreover, the various sources of uncertainty for this process are studied in detail. We then compare these predictions to experimental measurements. We additionally investigate the impact of the bb-quark initiated subprocesses.
