摘要这篇白色论文是对正在进行的关于简化暗物质（DM）模型的扩展和改进的讨论的一个投入。基于两个具体的例子，我们展示了如何现有的简化DM模型（SDMM）可以扩展到提供一个更准确，更全面的框架来解释和解释对撞机搜索。在第一个例子中，我们扩展了规范的SDMM与标量介体，包括混合与希格斯玻色子。我们表明，这种方法不仅提供了一个更好的描述的基本运动学特性，一个完整的模型将拥有，但也提供了选择使用这种更现实的标量混合模型类比较和联合收割机一致的搜索基于不同的实验签名。第二个例子概述了一个新的物理信号中观察到的可见通道可以连接到DM通过扩展一个简化的模型，包括有效的耦合。这种发现的情况下，使用最近观察到的过量的ATLAS和CMS的高质量双光子搜索的案例研究表明，这样一个务实的方法可以帮助实验搜索计划，以验证/伪造一个潜在的信号，并研究其潜在的性质。在白色白皮书的下一部分中，我们概述了SDMM的其他有趣选项，这些选项可以在未来进行更详细的研究。最后，我们讨论了DM的超对称模型的重要方面，以及这些如何有助于开发更完整的SDMM。
Abstract This White Paper is an input to the ongoing discussion about the extension and refinement of simplified Dark Matter (DM) models. Based on two concrete examples, we show how existing simplified DM models (SDMM) can be extended to provide a more accurate and comprehensive framework to interpret and characterise collider searches. In the first example we extend the canonical SDMM with a scalar mediator to include mixing with the Higgs boson. We show that this approach not only provides a better description of the underlying kinematic properties that a complete model would possess, but also offers the option of using this more realistic class of scalar mixing models to compare and combine consistently searches based on different experimental signatures. The second example outlines how a new physics signal observed in a visible channel can be connected to DM by extending a simplified model including effective couplings. This discovery scenario uses the recently observed excess in the high-mass diphoton searches of ATLAS and CMS for a case study to show that such a pragmatic approach can aid the experimental search programme to verify/falsify a potential signal and to study its underlying nature. In the next part of the White Paper we outline other interesting options for SDMM that could be studied in more detail in the future. Finally, we discuss important aspects of supersymmetric models for DM and how these could help to develop of more complete SDMM.
