摘要: Weakly interacting dark matter particles can be pair-produced at colliders and detected through signatures featuring missing energy in association with either QCD/EW radiation or heavy quarks. In order to constrain the mass couplings standard model particles, accurate precise predictions for production cross sections distributions are of prime importance. this work, we consider various simplified models s-channel mediators. We implement such FeynRules/MadGraph5_aMC@NLO framework, which allows include higher-order QCD corrections realistic simulations study their effect systematically. As a first phenomenological application, present jets top-quark pair LHC, next-to-leading accuracy QCD, including matching/merging parton showers. Our shows that via mediators have significant impact not only on total rates, but also shapes distributions. show inclusion effects results sizeable reduction theoretical uncertainties.
