Simplified Models and the Interpretation of Supersymmetry Searches — Michael Krämer1, Lennart Oymanns1, •Jory Sonneveld1, and Wolfgang Waltenberger2 — 1Institute for Theoretical Particle Physics and Cosmology, RWTH Aachen, Germany — 2Institut für Hochenergiephysik, Vienna, Austria
With new results and limits on constrained models of supersymmetry (SUSY) from the ATLAS and CMS collaborations at the LHC, questions arise what these limits imply for more general models of SUSY or other models for physics beyond the Standard Model. Since SUSY has a vast array of parameters, both collaborations also quantify their search results in terms of simplified models, augmenting the particle spectrum of the standard model with only a very limited set of new, hypothetical particles.
In our work presented here, we focus on "all-hadronic" (multijet plus missing transverse energy) searches at the LHC and set limits on simplified models parametrized by the squark, gluino and lightest SUSY particle (LSP) masses. This is a more general and complex parametrization than the one usually adopted by the LHC experiments, where a squark or gluino is decoupled from the simplified model. The limits we set will then be compared with limits which are directly deduced for specific SUSY and other new physics models to test the usability and possible interpretations of the simplified model results.
