我们研究了具有或不具有显式 CP 破坏的次小超对称标准模型中的希格斯扇区，重点关注单重场弱尺度期望值的情况。我们扫描大范围的参数空间，以确定允许的区域，要求电弱真空是有效势的全局最小值，并且具有中等规范耦合的中性希格斯玻色子比标准模型中希格斯玻色子的下界重。在允许的参数值组中，某些组产生这样的情况：轻希格斯玻色子与Z玻色子的耦合太弱，以致于在当前对撞机实验中不可能进行观察。对于这样的参数集，我们确定了大型强子对撞机中可达到的带电希格斯质量的上限。
We study the Higgs sector in the next-to-minimal supersymmetric standard model both with and without explicit CP violation, focusing on the case of a weak-scale expectation value of the singlet field. We scan a wide range of the parameter space to determine allowed regions by requiring that the electroweak vacuum be the global minimum of the effective potential and that the neutral Higgs bosons with moderate gauge coupling be heavier than the lower bound on the Higgs boson in the standard model. Among the allowed sets of parameter values, some sets yield the situation in which the light Higgs bosons couple with the Z boson too weakly for observation to be possible in present collider experiments. For such parameter sets, we determine an upper bound on the charged Higgs mass that is attainable in LHC.
