Limits on Simplified Models — •Lennart Oymanns¹, Jory Sonneveld¹, Michael Krämer¹, Wolfgang Waltenberger², Jan Heisig¹, and Lisa Edelhäuser¹ — ¹RWTH Aachen — ²HEPHY Vienna

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 test the usability of simplified models parametrized by the squark, gluino and lightest SUSY particle (LSP) masses. By comparing results of different variants of these simplified models we wish to point out the possibilities and limitations of using simplified models to estimate limits on SUSY and other BSM models.
