Abstract

We present a fully automated framework based on the FeynRules and MadGraph5 aMC@NLO programs that allows for accurate simulations of supersymmetric QCD processes at the LHC. Starting directly from a model Lagrangian that features squark and gluino interactions, event generation is achieved at the next-to-leading order in QCD, matching short-distance events to parton showers and including the subsequent decay of the produced supersymmetric particles. As an application, we study the impact of higher-order corrections in gluino pair-production in a simplified benchmark scenario inspired by current gluino LHC searches.

    • Methology: I did a search of http://arxiv.org/find/hep-ex/1/abs:+codes/0/1/0/all/0/1?quer... for "codes" in hep-ex entries at arXiv.org and reported the first few papers which actually contained "codes". (It appears that stemming is in place, as some papers only had 'code'.)…
