Production of top quark pairs at the LHC: NLO corrections and off-shell effects

With Run II, the Large Hadron Collider is entering a precision era. In order to compete with experimental measurements, precise and appropriate theoretical predictions should be computed. In that respect, the assessment of QCD corrections, electroweak (EW) corrections, and off-shell effects for Standard Model processes is of prime importance. To illustrate this, I present three recent computations where NLO QCD and EW corrections have been calculated for processes involving off-shell top quarks: the production of top-quark pairs decaying semi leptonically or fully leptonically and the latter production process in association with a Higgs boson.
