Abstract

Predictions for the Standard Model Effective Field Theory at the next-to-leading order accuracy in QCD, including parton-shower effects, have started to become available in the MadGraph5_aMC@NLO framework. In this talk we summarize some recent results for $t\bar t$, single top, $t\bar tZ/\gamma$, and $t\bar tH$ production channels at dimension six.
