Dark matter study from Lagrangian to data: in the FeynRules/MadGraph5_aMC@NLO framework

We present recent development of simulation tools to study dark matter at colliders as well as for astrophysical and cosmological observables in the F EYN R ULES /M AD G RAPH 5_ A MC@NLO framework. We show some results for simplified dark matter models with s-channel spin-1 mediators as an example.
