  If supersymmetry (SUSY) exists in nature and is a solution to the hierarchy
problem then it should be detectable at the TeV energy scale which the large
hadron collider (LHC) is now exploring. One of the main goals of the LHC is the
discovery or exclusion of the R-parity conserving minimal supersymmetric
standard model (MSSM). So far, the SUSY search results are presented in the
context of the constrained MSSM and other specific simplified SUSY models. A
model-independent analysis necessarily relies on the trigger-system of the LHC
detectors. By using the posterior samples of a 20-parameter MSSM, the
phenomenological MSSM, from a fit to indirect collider and cosmological data we
find that there is a significant volume in the MSSM parameter space that would
escape the standard trigger-systems of the detectors. As such, in the absence
of discovery in the current and future LHC runs, it would be difficult if not
impossible to exclude the MSSM unless some dedicated and special triggers are
commissioned or a Higgs boson with mass as predicted by the supersymmetric
models is not found.
