A comprehensive analysis of cosmological and collider constraints is presented for three simplified models characterised by a dark matter candidate (real scalar, Majorana fermion and real vector) and a coloured mediator (fermion, scalar and fermion respectively) interacting with the right-handed up quark of the Standard Model. Constraints from dark matter direct and indirect detection and relic density are combined with bounds originating from the re-interpretation of a full LHC run 2 ATLAS search targeting final states with multiple jets and missing transverse energy. Projections for the high-luminosity phase of the LHC are also provided to assess future exclusion and discovery reaches, which show that analogous future search strategies will not allow for a significant improvement compared with the present status. From the cosmological point of view, we demonstrate that thermal dark matter is largely probed (and disfavoured) by constraints from current direct and indirect detection experiments. These bounds and their future projections have moreover the potential of probing the whole parameter space when combined with the expectation of the high-luminosity phase of the LHC.

接近 t 通道简化的暗物质模型

对三个简化模型的宇宙学和对撞机约束进行了综合分析，这些模型的特征是暗物质候选者（实标量、马约拉纳费米子和实向量）和有色介体（分别为费米子、标量和费米子）与右手夸克相互作用标准模型。来自暗物质直接和间接检测和遗迹密度的约束与源自重新解释完整 LHC 运行 2 ATLAS 搜索的边界相结合，该搜索针对具有多个喷流和缺少横向能量的最终状态。还提供了对 LHC 高光度阶段的预测，以评估未来的排除和发现范围，这表明类似的未来搜索策略与当前状态相比不会有显着改善。从宇宙学的角度来看，我们证明了热暗物质在很大程度上受到当前直接和间接检测实验的限制（并且不受欢迎）。此外，当与 LHC 高亮度阶段的预期相结合时，这些边界及其未来预测具有探索整个参数空间的潜力。
