论文摘要
在这项工作中，我们考虑了使用惰性希格斯双重脚和真实标量单元的标准模型（SM）的扩展，以解决围绕暗物质（DM）的问题。在此模型中，CP-ODD和CP-EVEN中性惰性成分中最轻的是DM候选者的作用，其中模型参数受到许多理论和实验性约束。这些限制包括真空稳定性，扰动性，LEP负面搜索，Electroweak Precision测试，Higgs Di-Photon，Higgs Invisible和Higgs不确定的衰减，DM Relic Mentive and DM直接检测边界。使用这些约束，我们发现这些模型的允许参数空间相当大，可以在即将进行的对撞机和天体物理搜索中进行探索。
In this work, we consider an extension of the Standard Model (SM) with an inert Higgs doublet and a real scalar singlet, in order to address problems around the origin of dark matter (DM). In this model, the lightest among the CP-odd and CP-even neutral inert components plays the role of a DM candidate, where the model parameters are subject to many theoretical and experimental constraints. These constraints include vacuum stability, perturbativity, LEP negative searches, electroweak precision tests, Higgs di-photon, Higgs invisible and Higgs undetermined decays, DM relic density and DM direct detection bounds. Using these constraints, we find that the allowed parameter space for these models is quite sizeable and could be explored in upcoming collider and astrophysical searches.
