Lake Tahoe is famous for preserving dead bodies in good condition over many years, therefore it is a natural place to organize the SUSY conference. As a tribute to this event, here is a plot from a recent ATLAS meta-analysis:
A non-trivial question is what happens to these limits if one starts to fiddle with the remaining one hundred parameters of the MSSM. ATLAS tackles this question in the framework of the pMSSM, which is a version of the MSSM where all flavor and CP violating parameters are set to zero. In the resulting 19-dimensional parameter space, ATLAS picks a large number of points that reproduce the correct Higgs mass and are consistent with various precision measurements. Then they check what fraction of the points with a given m_gluino and m_neutralino survives the constraints from all ATLAS supersymmetry searches so far. Of course, the results will depend on how the parameter space is sampled, but nevertheless we can get a feeling of how robust are the limits obtained in simplified models. It is interesting that the gluino mass limits turn out to be quite robust. From the plot one can see that, for a light neutralino, it is difficult to live with m_gluino < 1.4 TeV, and that there's no surviving points with m_gluino < 1.1 TeV. Similar conclusion are not true for all simplified models, e.g., the limits on squark masses in simplified models can be very much relaxed by going to the larger parameter space of the pMSSM. Another thing worth noticing is that the blind spot near the m_gluino=m_neutralino diagonal is not really there: it is covered by ATLAS monojet searches.
The LHC run-2 is going slow, so we still have some time to play with the run-1 data. See the ATLAS paper for many more plots. New stronger limits on supersymmetry are not expected before next summer.
