Setting limits on supersymmetry using simplified models    [PDF]

C. Gütschow, Z. Marshall
Experimental limits on supersymmetry and similar theories are difficult to
set because of the enormous available parameter space and difficult to
generalize because of the complexity of single points. Therefore, more
phenomenological, simplified models are becoming popular for setting
experimental limits, as they have clearer physical implications. The use of
these simplified model limits to set a real limit on a concrete theory has not,
however, been demonstrated. This paper recasts simplified model limits into
limits on a specific and complete supersymmetry model, minimal supergravity.
Limits obtained under various physical assumptions are comparable to those
produced by directed searches. A prescription is provided for calculating
conservative and aggressive limits on additional theories. Using acceptance and
efficiency tables along with the expected and observed numbers of events in
various signal regions, LHC experimental results can be re-cast in this manner
into almost any theoretical framework, including non-supersymmetric theories
with supersymmetry-like signatures.
