超对称性在额外维度中的几何破缺自然会导致超粒子的近简并谱，从而改善了LHC当前搜索的边界。我们提出了一个最小的这样的模型与一个额外的维度，并表明，它导致可行的现象，尽管事实上，它基本上有两个自由参数比传统的CMSSM。由于几何破缺的普适性，该理论不受超对称味道或CP问题的影响，并且在标量顶部扇区自动产生近最大混合，|A_t| ~ 2 m_{\tilde{t}}来增加希格斯玻色子的质量。尽管这个理论的结构相当有限，但它比许多超对称模型更不精确。
Supersymmetry broken geometrically in extra dimensions naturally leads to a nearly degenerate spectrum for superparticles, ameliorating the bounds from the current searches at the LHC. We present a minimal such model with a single extra dimension, and show that it leads to viable phenomenology despite the fact that it essentially has two less free parameters than the conventional CMSSM. The theory does not suffer from the supersymmetric flavor or CP problem because of universality of geometric breaking, and automatically yields near-maximal mixing in the scalar top sector with |A_t| ~ 2 m_{\tilde{t}} to boost the Higgs boson mass. Despite the rather constrained structure, the theory is less fine-tuned than many supersymmetric models.
