Title: Hadroproduction of four top quarks in the powheg box

Abstract

We present a new Monte Carlo event generator for the hadronic production of four top quarks in the powheg box framework. Besides the dominant next-to-leading order QCD corrections at $O (α_{s}^{5})$ we also include all subleading electroweak productions channels at leading-order accuracy. We validate our theoretical predictions by comparing to parton-shower matched predictions obtained within the mc@nlo framework for stable top quarks. Furthermore, we investigate in detail the various sources of theoretical uncertainties. Finally, we investigate a single lepton plus jets signature to study for the first time the impact of the electroweak production modes as well as spin-correlation effects at the fiducial level.
