Summary
The LHC experiments typically present their results for supersymmetry
searches in terms of simplified low-scale models. These models can
fail to capture the complexity of more realistic SUSY scenarios, in
which many different sparticles have competing production and decay
mechanisms; consideration of which can reduce the lower limits on
sparticle masses. We have reinterpreted 20 of the most up-to-date
ATLAS new physics searches in terms of the more general
phenomenological- MSSM, a subset of the full MSSM containing the 19
most relevant parameters. This provides an ideal laboratory to study
the impact of ATLAS searches during Run 1 of the LHC. More than
300,000 pMSSM model points were studied, each satisfying all relevant
experimental constraints including Dark Matter, heavy flavour and
precision electroweak measurements. The results allow one to see
where simplified model limits are robust, and where there is room for
new physics still to be hiding, in some cases even at surprisingly low
masses. This is the first time such a large-scale study of this kind
has been attempted by an LHC collaboration.
