where the mixing and loop contributions are below m h but where in most models, the soft SUSY breaking up-Higgs mass m H u is driven to large, TeV-scale negative values (in order to break electroweak symmetry). Then, to maintain the measured value of m h = 125 GeV, one must tune the superpotential mass term μ to some large positive value. Alternatively, for natural SUSY, one may expect that m H u runs to small negative values, in which case both μ and | m H u | are of order 100–200 GeV. This already leads to a prediction: since μ is supersymmetric and feeds mass to both SM particles (W, Z, h) and superpartners (higgsinos), then it is expected from the natural MSSM that light higgsinos exist nearby to the 100–200 GeV scale. This simple realization has profound implications for WSS collider and dark matter searches.
