我们研究了由高尺度超对称性和分裂超对称性预测的希格斯质量的范围，使用由最小场含量确定的希格斯四次耦合的匹配条件。在分裂超对称的情况下，我们第一次计算了完整的次到首阶修正，包括两圈重整化群方程和一圈阈值效应。这些修正使预测的希格斯粒子质量减少了几个GeV。我们调查的影响，最近的大型强子对撞机希格斯粒子搜索超对称性破缺的规模。特别是，我们表明，127 GeV的希格斯质量的上限意味着分裂超对称的规模上的上限约为108 GeV，而没有确切的结论还可以得出高尺度超对称。
We study the range of Higgs masses predicted by High-Scale Supersymmetry and by Split Supersymmetry, using the matching condition for the Higgs quartic coupling determined by the minimal field content. In the case of Split Supersymmetry, we compute for the first time the complete next-to-leading order corrections, including two-loop renormalization group equations and one loop threshold effects. These corrections reduce the predicted Higgs mass by a few GeV. We investigate the impact of the recent LHC Higgs searches on the scale of supersymmetry breaking. In particular, we show that an upper bound of 127 GeV on the Higgs mass implies an upper bound on the scale of Split Supersymmetry of about 108GeV, while no firm conclusion can yet be drawn for High-Scale Supersymmetry.
