论文摘要
在近乎最小的超对称标准模型中，与Singlet Higgs相对应的质量术语与单利诺相互作用状态之间存在很强的相关性，这两种状态都与参数$κ$成比例。如果此参数很复杂，则与最小情况不同，在希格斯（Higgs）以及模型的中性扇区中发生了明确的CP侵略。一小部分$κ$通常会产生$ \ cal {o} $（10）GEV最轻的中性诺，具有主导的单利诺组件。在这种情况下，$κ$的阶段除了修改五个希格斯玻色子的性质外，还可能对中性侵蚀暗物质的现象学产生至关重要的影响。在这项研究中，我们首先研究了这种影响对暗物质解决方案的遗物丰度，该溶液的质量为100 GEV质量，该模型的参数空间构型获得了与各种当前实验数据一致的模型。
In the Next-to-Minimal Supersymmetric Standard Model there is a strong correlation between the mass terms corresponding to the singlet Higgs and the singlino interaction states, both of which are proportional to the parameter $κ$. If this parameter is complex, explicit CP-violation occurs in the Higgs as well as the neutralino sectors of the model at the tree level, unlike in the minimal scenario. A small magnitude of $κ$ typically yields a $\cal{O}$(10) GeV lightest neutralino with a dominant singlino component. In such a scenario, the phase of $κ$, beside modifying the properties of the five Higgs bosons, can also have a crucial impact on the phenomenology of the neutralino dark matter. In this study we perform a first investigation of this impact on the relic abundance of the dark matter solutions with sub-100 GeV masses, obtained for parameter space configurations of the model that are consistent with a variety of current experimental data.
