我们将S-MSSM——具有显式{mu}项和超对称质量项的最小超对称标准模型的单重态扩展——嵌入到一个规范介导的超对称破缺方案中。我们发现，通过免除单线态解决{mu}问题的责任，我们反而能够解决小层次问题。具体来说，我们发现即使将S-MSSM最小程度地嵌入到量规介导的方案中，我们也可以很容易地将最轻的希格斯质量提高到114 GeV以上，同时保持顶部夸克低于TeV尺度，保持量规耦合的微扰统一，并且无需调整模型的其他参数。
We embed the S-MSSM--a singlet extension of the minimal supersymmetric standard model with an explicit {mu}-term and supersymmetric mass term--in a gauge-mediated supersymmetry breaking scheme. We find that by absolving the singlet of its responsibility for solving the {mu}-problem, we are instead able to solve the little hierarchy problem. Specifically, we find that even with a minimal embedding of the S-MSSM into a gauge-mediated scheme, we can easily raise the lightest Higgs mass above 114 GeV, while keeping top squarks below the TeV scale, maintaining perturbative unification of the gauge couplings, and without tuning the other parameters of the model.
