pMSSM studies with ATLAS and CMS

The ATLAS and CMS collaborations conducted a large number of searches for supersymmetry during Run-1 of the LHC. No statistically significant excess was found and so limits have been placed on the masses of spartcles. These limits are usually interpreted in terms of low-scale simplified models, however, these models can fail to capture the complexity of full MSSM models and therefore provide over-optimistic exclusion. Both the ATLAS and CMS collaborations have embarked upon large-scale studies to combine their most sensitive searches for supersymmetry and analysed their impact on the 19-parameter phenomenological MSSM; allowing them to take into account all relevant dark matter, heavy flavour and precision electroweak measurements, as well as the constraints from the LHC searches. The results allow one to see where there is room for new physics still to be hiding, in some cases at surprisingly low masses.
