An important tool for interpreting LHC searches for new physics aresimplified models. They are characterized by a small number of parameters andthus often rely on a simplified description of particle production and decaydynamics. Considering the production of squarks of the first two generations wecompare the interpretation of current LHC searches for hadronic jets plusmissing energy signatures within simplified models with the interpretationwithin a complete supersymmetric model. Although we find sizable differences inthe signal efficiencies, in particular for large supersymmetric particlemasses, the differences between the mass limits derived from a simplified modeland from the complete supersymmetric model are moderate given the current LHCsensitivity. We conclude that simplified models provide a reliable tool tointerpret the current hadronic jets plus missing energy searches at the LHC ina more model-independent way.
