我们计算希格斯粒子的质量在一个计划中，超对称性被打破在一个大规模的M SS远高于电弱规模M EW。在M SS以下，我们假设只剩下带有微调希格斯势的SM。在标准的统一假设下，我们可以计算希格斯粒子的质量作为超对称破缺尺度M SS的函数。对于M SS = 10 10 GeV，得到m H= 126±3 GeV，与CMS和ATLAS的结果一致。对于较低的M SS值，希格斯粒子的质量值趋向于微调的MSSM（m H = 130 GeV）。这些结果支持了这样一种观点，即在LHC上测得的希格斯粒子的质量值可以被认为是在某些（不一定是低）质量尺度上超对称性存在的间接证据。
We compute the mass of the Higgs particle in a scheme in which SUSY is broken at a large scale M SS well above the electroweak scale M EW. Below M SS one assumes one is just left with the SM with a fine-tuned Higgs potential. Under standard unification assumptions one can compute the mass of the Higgs particle as a function of the SUSY breaking scale M SS. For M SS≳ 10 10 GeV one obtains m H= 126±3 GeV, consistent with CMS and ATLAS results. For lower values of M SS the values of the Higgs mass tend to those of a fine-tuned MSSM with m H≲ 130 GeV. These results support the idea that the measured value of the Higgs mass at LHC may be considered as indirect evidence for the existence of SUSY at some (not necessarily low) mass scale.
