  The ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN have
searched for signals of new physics, in particular for supersymmetry. The data
collected until 2012 at center-of-mass energies of 7 and 8 TeV and integrated
luminosities of 5 fb^-1 and 20 fb^-1, respectively, agree with the expectation
from standard model processes. Constraints on supersymmetry have been
calculated and interpreted in different models. Limits on supersymmetry
particle masses at the TeV scale have been derived and interpreted generally in
the context of simplified model spectra. The constrained minimal supersymmetric
standard model is disfavored by the experimental results. Natural supersymmetry
scenarios with low supersymmetry particle masses remain possible in multiple
regions, for example in those with compressed spectra, that are difficult to
access experimentally. The upgraded LHC operating at 13 TeV is gaining
sensitivity to the remaining unexplored SUSY parameter space.
