In this article, we present a method to calculate a posteriori event weightsat next-to-leading-order (NLO) QCD accuracy for a given jet event defined bythe (anti-)$k_t$ algorithm relying on the conventional $2\to 1$ recombination.This is an important extension compared to existing Monte-Carlo tools whichgenerate jet events together with the corresponding weight but do not allow oneto calculate the weight for a given event. The method can be used to generateunweighted events distributed according to the fixed-order NLO cross section.In addition, the method allows one to calculate NLO accurate weights for eventsrecorded by experiments. The potential of this ability is illustrated byapplying the Matrix Element Method (MEM) to single top-quark events generatedwith POWHEG in combination with Pythia. For the first time, a systematic studyof parton shower effects within the MEM is provided. The method is completelygeneral and can be applied to arbitrary LHC processes.
