论文摘要
我们根据对撞机和暗物质搜索限制以及对强一阶Electroweak Electroweak相变（EWPT）的要求，使Higgs Doublet模型（IDM）进行了全局拟合。这些表明仍然存在与观察性约束兼容的IDM参数空间。特别是，数据和理论要求提出了对存在标量暗物质候选者100 GEV的存在的假设。这主要是由于EWPT约束朝着较低的质量伸出。 Electroweak Precision测量值，暗物质直接检测极限以及获得足够强大的一阶EWPT的条件，都具有强烈的依赖性，有时在相对方向上，对IDM标量之间的质量分配。
We made global fits of the inert Higgs doublet model (IDM) in the light of collider and dark matter search limits and the requirement for a strongly first-order electroweak phase transition (EWPT). These show that there are still IDM parameter spaces compatible with the observational constraints considered. In particular, the data and theoretical requirements imposed favour the hypothesis for the existence of a scalar dark matter candidate around 100 GeV. This is mostly due to the pull towards lower masses by the EWPT constraint. The impact of electroweak precision measurements, the dark matter direct detection limits, and the condition for obtaining a strongly enough first-order EWPT, all have strong dependence, sometimes in opposing directions, on the mass splittings between the IDM scalars.
