Interpretation of Searches for Supersymmetry
Abstract
The results of CMS searches for Supersymmetry are interpreted in the context of
Simplified Models.
These results are based on data samples
with a corresponding integrated luminosity of up to 4.98\fbinv produced
in protonproton collisions at a centerofmass energy
of 7~TeV collected by the CMS experiment at the LHC.
This analysis provides a compilation of acceptance predictions and cross section upper limits
for a range of Simplified Models and mass parameters. The results provide information that can
be used to constrain other theoretical models. They also provide a comparison of different CMS search strategies.
