  An important tool for interpreting LHC searches for new physics are
simplified models. They are characterized by a small number of parameters and
thus often rely on a simplified description of particle production and decay
dynamics. Considering the production of squarks of the first two generations we
compare the interpretation of current LHC searches for hadronic jets plus
missing energy signatures within simplified models with the interpretation
within a complete supersymmetric model. Although we find sizable differences in
the signal efficiencies, in particular for large supersymmetric particle
masses, the differences between the mass limits derived from a simplified model
and from the complete supersymmetric model are moderate given the current LHC
sensitivity. We conclude that simplified models provide a reliable tool to
interpret the current hadronic jets plus missing energy searches at the LHC in
a more model-independent way.
