The Simplified Models Approach to Constraining Supersymmetry — •Genessis Perez R¹ and Suchita Kulkarni² — ¹Institut für Theoretische Physik, Karlsruher Institut für Technologie (KIT), Wolfgang-Gaede-Str. 1, 76131 Karlsruhe Germany — ²Laboratoire de Physique Subatomique et de Cosmologie, Université Grenoble Alpes, CNRS IN2P3, 53 Avenue des Martyrs, 38026 Grenoble France

The interpretation of the experimental results at the LHC are model dependent, which implies that the searches provide limited constraints on scenarios such as supersymmetry (SUSY). The Simplified Models Spectra (SMS) framework used by ATLAS and CMS collaborations is useful to overcome this limitation. SMS framework involves a small number of parameters (all the properties are reduced to the mass spectrum, the production cross section and the branching ratio) and hence is more generic than presenting results in terms of soft parameters.

In our work, the SMS framework was used to test Natural SUSY (NSUSY) scenario. To accomplish this task, two automated tools (SModelS and Fastlim) were used to decompose the NSUSY parameter space in terms of simplified models and confront the theoretical predictions against the experimental results. The achievement of both, just as the strengths and limitations, are here expressed for the NSUSY scenario.
