Development and Analysis of Simplified Models in the Search for Supersymmetry with Tau Leptons in the Final State at the ATLAS Experiment — Philip Bechtle, Klaus Desch, Till Nattermann, •Oliver Ricken, Steffen Schaepe, and Martin Schultens — University of Bonn

A recently pursued approach in the search for Supersymmetry (SUSY) as an extension of the Standard Model is the exploitation of so-called Simplified Models. While the search for full SUSY models requires the investigation of all possible decay topologies the model allows for, the search exploiting Simplified Models can be reduced to a single decay topology. As a consequence, Simplified Models offer a rather easily accessible but reduced parameter space to parametrise the outcome of SUSY searches. Simplified Models could provide hints where to look for SUSY using full model analyses and set limits on model parameters.
This talk introduces a recently developed Simplified Model of strong squark production along with two auxilliary models of electroweak processes. For the primary model and one auxilliary model the obtained exclusion limits on the model parameters are presented and discussed. Moreover, the results of detailled analyses regarding dominant and subdominant parameters of the primary model studied in the two auxilliary models are shown. Motivated by these studies, the development and prospects of optimal parametrisation of future Simplified Models of strong production is addressed.
