Description

In this work, we present limits on natural supersymmetry inspired scenarios based on searches in data taken during run 1 of the LHC. We consider a set of 22000 model points in a six dimensional parameter space. The resulting mass spectra feature higgsinos as the lightest supersymmetric particle, as well as relatively light third generation SU(2) doublet squarks and SU(2) singlet stops and gluinos while assuming a Standard Model like Higgs boson. All remaining supersymmetric particles and Higgs bosons are assumed to be decoupled. We check each parameter set against a large number of LHC searches as implemented in the public code CheckMATE. These searches show a considerable degree of complementarity, i.e. in general many searches have to be considered in order to check whether a given scenario is allowed. We delineate allowed and excluded regions in parameter space. For example, we find that all scenarios where either mt̃ 1<230 GeV or mg̃ <440 GeV are clearly excluded, while all model points where mt̃ 1>660 GeV and mg̃ >1180 GeV remain allowed.
