论文摘要
具有非普遍HIGGS质量的近临界超对称标准模型（NMSSM），或半约束的NMSSM（SCNMSSM），将最小的超对称标准模型（MSSM）扩展到单元上的超级领域，并假设除HIGGS部门以外的通用条件。它不仅可以保持完全约束的MSSM和NMSSM的简单性和优雅，并放松在发现125-GEV Higgs Boson之后所面临的紧张局势，而且还可以预测一种异国情调的现象，它是Higgs Higgs衰减到一对轻单元支配的标量（$ 10 \ sim \！\！\！\！\！60 \ c;该条件可以根据Smlike Higgs和Light标量的身份分类为三种情况：（i）灯标量为CP-ODD，而Smike Higgs为$ H_2 $; （ii）灯标量为CP-ODD，Smike Higgs为$ H_1 $; （iii）灯标量为CP-E，而Smike Higgs为$ H_2 $。 In this work, we compare the three scenarios, checking the interesting parameter schemes that lead to the scenarios, the mixing levels of the doublets and singlets, the tri-scalar coupling between the SM-like Higgs and a pair of light scalars, the branching ratio of Higgs decay to the light scalars, and sensitivities in hunting for the exotic decay at the HL-LHC and the future lepton CEPC，FCC-EE和ILC等山脉。
The next-to minimal supersymmetric standard model (NMSSM) with non-universal Higgs masses, or the semi-constrained NMSSM (scNMSSM), extend the minimal supersymmetric standard model (MSSM) by a singlet superfield and assume universal conditions except for the Higgs sector. It can not only keep the simpleness and grace of the fully constrained MSSM and NMSSM, and relax the tension that they face after the 125-GeV Higgs boson discovered, but also predict an exotic phenomenon that Higgs decay to a pair of light singlet-dominated scalars ($10\!\sim\! 60\;{\rm GeV}$). This condition can be classified to three scenarios according to the identities of the SM-like Higgs and the light scalar: (i) the light scalar is CP-odd, and the SM-like Higgs is $h_2$; (ii) the light scalar is CP-odd, and the SM-like Higgs is $h_1$; (iii) the light scalar is CP-even, and the SM-like Higgs is $h_2$. In this work, we compare the three scenarios, checking the interesting parameter schemes that lead to the scenarios, the mixing levels of the doublets and singlets, the tri-scalar coupling between the SM-like Higgs and a pair of light scalars, the branching ratio of Higgs decay to the light scalars, and sensitivities in hunting for the exotic decay at the HL-LHC and the future lepton colliders such as CEPC, FCC-ee, and ILC.
