我们探索了一种基于最小 SU(5) 规范组和希格斯表示的缺失伙伴模型,假设一个超级 GUT CMSSM 场景,其中软超对称破缺参数在高于 GUT 尺度的某些高尺度上是通用的。我们确定了与宇宙暗物质密度、测量的希格斯质量和实验下限一致的参数空间区域。这些约束可以沿着具有 3.5-5 的超级 GUT CMSSM 中的停止共湮灭带同时得到满足,其中输入高吉诺质量为 15-25 TeV,在通过大 GUT Higgs 表示进行强重正化后对应于 2.5-5 TeV 和 13-20 TeV,轻味夸克明显更重。我们发现,在参数空间允许的范围内,在 JUNO、DUNE 和 Hyper-Kamiokande 实验的下一代搜索范围内。
We explore a missing-partner model based on the minimal SU(5) gauge group with,andHiggs representations, assuming a super-GUT CMSSM scenario in which soft supersymmetry-breaking parameters are universal at some high scaleabove the GUT scale. We identify regions of parameter space that are consistent with the cosmological dark matter density, the measured Higgs mass and the experimental lower limit on. These constraints can be satisfied simultaneously along stop coannihilation strips in the super-GUT CMSSM with3.5–5 where the input gaugino mass15–25 TeV, corresponding after strong renormalization by the large GUT Higgs representations betweenandto2.5–5 TeV and13–20 TeV, with the light-flavor squarks significantly heavier. We find thatyears throughout the allowed range of parameter space, within the range of the next generation of searches with the JUNO, DUNE and Hyper-Kamiokande experiments.
