The results of searches for supersymmetry by the CMS experiment are interpreted in the framework of simpliﬁed models. The results are based on data corresponding to an integrated luminosity of 4.73 to 4.98 fb − 1 . The data were collected at the LHC in proton–proton collisions at a center-of-mass energy of 7 TeV. This paper describes the method of interpretation and provides upper limits on the product of the production cross section and branching fraction as a function of new particle masses for a number of simpliﬁed models. These limits and the corresponding experimental acceptance calculations can be used to constrain other theoretical models and to compare different supersymmetry-inspired analyses. the T3, T5 and TChiSlepSlep models, the mass of the intermediate particle is deﬁned by the relation m int = x m mother + ( 1 − x ) m LSP . For the T3w and T5zz models, the results are presented for x = 0.25, 0.5, 0.75, while for the T3lh, T5lnu, and TChiSlepSlep models, x = 0.5. The lowest mass value for m mother depends on the particular analysis and the simpliﬁed model.
