SModelS is a tool designed for the interpretation of the LHC searches
for Beyond Standard Model (BSM) physics based on Simplified Models
Spectra (SMS).

SModelS performs the decomposition of arbitrary BSM scenarios
featuring a Z2 symmetry into their SMS components, and evaluates the
theoretical predictions for their production cross sections. These
predictions are then compared with the results from the LHC searches
implemented in a comprehensive and up-to-date database, in the form of
cross section upper limit maps or signal efficiency maps.

In particular the usage of efficiency maps is one of the main new
features of the upcoming version SModelS v1.1. It allows for the
combination of different simplified models for the evaluation of cross
section upper limits, thus increasing the constraining power of

As an application, we show how SModelS has been used for the study of
specific supersymmetric models not only to constrain the theory's
parameter space, but also to highlight interesting regions currently
not covered by the experiments. This way we can also give feedback to
the experiments for where to look next.
