我们根据底层 Z4 或 Z8R 对称性确定 NMSSM 的通用版本所需的微调程度。我们发现它明显小于 MSSM 或 NMSSM 中的质量，并且扩展了具有可接受微调的希格斯质量范围。值得注意的是，希格斯粒子的质量约为 130 GeV，实现了最小的微调。
We determine the degree of fine-tuning needed in a generalised version of the NMSSM that follows from an underlying Z4or Z8R-symmetry. We find that it is significantly less than is found in the MSSM or NMSSM and extends the range of Higgs mass that have acceptable fine-tuning. Remarkably the minimal fine-tuning is achieved for Higgs masses of around 130 GeV.
