论文摘要
对三个简化模型进行了对宇宙学和对撞机约束的全面分析,这些简化模型以暗物质候选者(真正的标量,Majoraana fermion和真实矢量)和有色介体(分别为fermion,scalial和fermion)与标准模型的右手夸克相互作用。暗物质直接和间接检测的约束和遗物密度与界限结合起来,该边界源于重新解释完整的LHC运行2 Atlas搜索目标,该搜索目标是具有多个Jets和缺少横向能量的最终状态。还提供了LHC高光度阶段的预测,以评估未来的排除和发现范围,这表明与当前状态相比,类似的未来搜索策略将不允许显着改善。从宇宙学的角度来看,我们证明了热暗物质是通过当前直接和间接检测实验的约束来探测(和分类)的。此外,这些边界及其未来的预测具有探测整个参数空间的潜力,与LHC的高光度阶段的期望结合使用。
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.
