Duration: 15'+5'
The simulation of processes involving heavy unstable particles, like the top quark, holds significant importance in LHC physics. In this contribution, we address the exclusive simulation of top-quark pair production with dileptonic decays, including the non-resonant diagrams, interferences, and off-shell effects arising from the finite top-quark width. Our simulations, utilizing the mg5_aMC@NLO program, achieve next-to-leading order accuracy in QCD and is matched to parton showers through the MC@NLO method. We present phenomenological results with direct relevance to the 13 TeV LHC. We benchmark the impact of the off-shell effects on representative distributions relevant for top mass extractions, and compare our simulation to lower accuracy simulations and to data.
