Introducing SModelS: a tool for testing LHC results using simplified models

I present a new tool, SModelS, for decomposing generic SUSY spectra
into simplified models (SMS) topologies and testing them against the
existing SMS limits from the LHC. This tool is in principle applicable
to any beyond the Standard Model theory respecting a Z2 symmetry. I
will explain the working principle of SModelS, as well as its
validation and limitations. As a show-case example, I will then
present its application for the study of light neutralino dark matter
in the MSSM (arXiv:1308.3735). Here I will discuss the viability of
light neutralino DM with mass below 35 GeV consistent with LHC bounds.
This is a promising way to probe the light neutralino dark matter
scenario in the next run of the LHC.
