论文摘要
我们研究了最简单的可行暗物质模型，具有真实的单线标量，类似矢量的单线和Doublet Lepton。我们发现在新的Yukawa耦合的影响下，标量暗物质参数空间的允许区域有相当大的增强。 Yukawa耦合与Fermion部门相关联，在很大程度上占据了深色的参数空间，满足了宇宙的当前遗物密度。 dilepton $+\ slashed {e} _t $签名是由新的费米子扇区引起的，可以在大型强子对撞机（LHC）上观察。我们在14个TEV LHC实验的上下文中执行此类分析，未来的集成光度为3000 $ {\ rm fb^{ - 1}} $。我们发现，LHC实验可以探测参数空间的大区域。通过进行详细的基于剪切的对撞机分析，可以分析此渠道中直接重电费米搜索的预计排除/发现范围。预计的排除轮廓最高可达$ 1050-1380〜 {\ rm gev} $ 3000 $ {\ rm fb^{ - 1}} $，用于轻微的暗物质$ \ Mathcal $ \ Mathcal {O}（10）$ GEV，$ pp \ rightarrow e_1^\ pm pm e _1^pm pm e _1 l^\ pm s \ rightarrow ll + \ slashed {e} _t $ channel。
We study a simplest viable dark matter model with a real singlet scalar, vector-like singlet and a doublet lepton. We find a considerable enhancement in the allowed region of the scalar dark matter parameter spaces under the influence of the new Yukawa coupling. The Yukawa coupling associate with the fermion sector heavily dominant the dark matter parameter spaces satisfying the current relic density of the Universe. Dilepton$+\slashed{E}_T$ signature arising from the new fermionic sector can observe at Large Hadron Collider (LHC). We perform such analysis in the context of 14 TeV LHC experiments with a future integrated luminosity of 3000 ${\rm fb^{-1}}$. We found that a large region of the parameter spaces can be probed by the LHC experiments. The projected exclusion/discovery reach of direct heavy charged fermion searches in this channels is analyzed by performing a detailed cut based collider analysis. The projected exclusion contour reaches up to $1050-1380~{\rm GeV}$ for 3000 ${\rm fb^{-1}}$ for a light dark matter $\mathcal{O}(10)$ GeV from searches in the $ pp \rightarrow E_1^\pm E_1^\mp, E_1^\pm\rightarrow l^\pm S \rightarrow ll + \slashed{E}_T$ channel.
