论文摘要
结合风味暗物质的模型为暗物质问题提供了优雅的解决方案，避免了紧密的LHC并在简单的WIMP模型上进行了直接指导约束。在深度最小的风味中，一个简单的风味深色物质框架，具有新的风味侵犯来源，热冻结的限制，直接检测实验和风味物理学为这些模型创造了明确定义的基准场景。我们研究了四种情况下的LHC现象学，重点是最终状态，在这些状态下，没有喷气机伴随着一个顶级夸克，一台来自光夸克的碎片或$ b $ tage的喷气机。对于这些签名，我们进行了现实的LHC分析，我们表明，与现有的支持Flavour的LHC分析相比，提出的分析将增加四个基准的参数空间覆盖率。最终，我们显示了在14 TEV和高光度LHC的全部LHC统计数据中所考虑的签名的预计发现潜力。
Models incorporating flavoured dark matter provide an elegant solution to the dark matter problem, evading the tight LHC and direct direction constraints on simple WIMP models. In Dark Minimal Flavour Violation, a simple framework of flavoured dark matter with new sources of flavour violation, the constraints from thermal freeze-out, direct detection experiments, and flavour physics create well-defined benchmark scenarios for these models. We study the LHC phenomenology of four such scenarios, focusing on final states where a single top quark is produced accompanied by no jets, one jet from the fragmentation of light quarks or a $b$-tagged jet. For each of these signatures we develop a realistic LHC analysis, and we show that the proposed analyses would increase the parameter space coverage for the four benchmarks, compared to existing flavour-conserving LHC analyses. Finally we show the projected discovery potential of the considered signatures for the full LHC statistics at 14 TeV, and for the High Luminosity LHC.
