Summary of SUSY constraints from ATLAS using the phenomenological MSSM

A summary of the ATLAS collaboration's sensitivity to $R$-parity conserving supersymmetry is presented. A total of 22 beyond-the-Standard-Model searches for exotic particles, heavy Higgs bosons and supersymmetric partner particles have been combined to test the validity of a large class of supersymmetric scenarios. In this selection of models, all relevant dark matter, heavy flavour and precision electroweak measurements have been taken into account. The results of these searches are interpreted in the 19-parameter phenomenological-MSSM, and allow one to see where there is room for new physics still to be hiding, in some cases at surprisingly low masses. This is the first time such a large-scale study of this kind has been attempted by an LHC collaboration.
