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$+{\mathrm{E̸}}_T$ 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 ${\text{fb}}^{-1}$. 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 channel is analyzed by performing a detailed cut based collider analysis. The projected exclusion contour reaches up to $1050-1380\text{GeV}$ for 3000 $\mathrm{f}{\mathrm{b}}^{-\mathrm{1}}$ for a light dark matter $\mathcal{O}(10)$ GeV from searches in the $pp\to E_1^{\pm }{E}_1^{\mp },E_1^{\pm }\to l^{\pm }S\to ll+{\mathrm{E̸}}_T$ channel.

我们研究了一个简单的可行暗物质模型，该模型具有真实的单重态标量，类似矢量的单重态和双重态轻子。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了相当大的增强。汤川耦合与费米子界联系在一起，暗物质参数空间占据了主导地位，满足了宇宙当前的文物密度。Dilepton$+{̸}_{Ť}$在大型强子对撞机（LHC）上可以观察到由新的铁电离子产生的签名。我们在14个TeV LHC实验的背景下进行此类分析，未来的综合光度为3000${\text{fb}}^{-\mathrm{1个}}$。我们发现，LHC实验可以探查大范围的参数空间。通过执行基于详细切割的对撞机分析，可以分析此通道中直接重电荷费米子搜索的预计排除/发现范围。预计的排除轮廓达到$1050-1380\text{GeV}$ 为3000 $\mathrm{F}{\mathrm{b}}^{-\mathrm{1个}}$ 对于浅暗物质 $\mathcal{Ø}（10）$ GeV来自 $pp\to {Ë}_{\mathrm{1个}}^{\pm }{Ë}_{\mathrm{1个}}^{\mp }，{Ë}_{\mathrm{1个}}^{\pm }\to {升}^{\pm }\mathrm{小号}\to 升升+{̸}_{Ť}$ 渠道。
